SUMMARY:Polymer Chemistry and Lutherie: The Materials of Fretted Instrument
DESCRIPTION:We kick-off this sensory ride with Dr. Steven Pollack who doubles as a science fellow at Carbon\, Inc. and a luthier for Yellow Rose Lutherie of Redwood City. In his talk titled\, “Polymer Chemistry and Lutherie: The Materials of Fretted Instruments”\, he discusses the polymers in the guitar that can influence the quality of the instrument’s sound\, both positively and negatively.  Damping or enhancing specific frequencies via resonance gives the acoustic guitar its “voice.” Please join us for this melodious talk on 18 February 2021 at 7:00 pm PST. \nThis presentation was recorded and can be viewed here.

SUMMARY:Stereoselective Construction of Challenging C - C Bonds: Total Synthesis of Complex Bioactive Agents
DESCRIPTION:Abstract\nThe central premise of the research in my group focuses on developing novel synthetic transformations that permit the expeditious total synthesis of complex bioactive natural products. A unique and striking feature of the program is the ability to access new chemical reactivity\, which in conjunction with detailed mechanistic studies\, permits the development of sophisticated multi-component processes for the stereoselective construction of complex molecular architectures. \nOne of the group’s ongoing goals is developing allylic coupling reactions using rhodium-allyl electrophiles with an array of carbon and heteroatom pronucleophiles. Indeed\, this process now represents a powerful and highly regio- and stereoselective sp3 cross-coupling reaction for target-directed  synthesis.  In recent work\, we have focused on the alternative umpolung reaction paradigm\, which probes the merit of the corresponding allylic metal anions in the context of novel dynamic kinetic resolution reactions of a\,b-unsaturated aldehydes that function as both acyl anions and homoenolates in novel cross-coupling reactions. \nIn the context of total synthesis\, we have recently developed a concise\, efficient and scalable total synthesis of the complex bioactive sesquiterpene natural product\, Thapsigargin. This agent was isolated from the Mediterranean plant Thapsia garganica and provided a highly selective subnanomolar inhibitor of intracellular calcium ion transport enzymes\, which induces apoptosis\, leading to cell death. Mipsagargin\, a prodrug of Thapsigargin\, is currently in the late-stage clinical trials to treat liver\, brain\, prostate and kidney cancer. The seminar will outline the evolution of these useful developments and their impact on synthetic and medicinal chemistry. \nSpeaker bio\nAndrew Evans is the Alfred  R. Bader Chair of Organic Chemistry and a Tier 1 Canada Research Chair in Organic and Organometallic Chemistry in the Department of Chemistry at Queen’s University. He received a B.Sc. with honors in Applied Chemistry at Newcastle Polytechnic in 1987 and a Ph.D. at the University of Cambridge in 1991 under the supervision of Andrew B. Holmes\, FRS. He then completed postdoctoral studies with Philip D. Magnus\, FRS\, at the University of Texas at Austin as a NATO Postdoctoral Fellow. In 1993\, he initiated his independent career at the University of Delaware\, where he rose through the ranks to Professor before moving to Indiana University in 2001. In 2006\, he moved to the University of Liverpool\, where he was the Heath Harrison Chair of Organic Chemistry\, before moving to his current position in July 2012. \nHis research accomplishments have been globally recognized\, including the Changjiang Scholar Award\, ACS Cope Scholar Award\, ACS Fellow\, RSC Pedler Award\, the Royal Society Wolfson Research Merit Award\, Pfizer Award for Creativity in Organic Chemistry\, Johnson and Johnson Focused Giving Award\, GlaxoWellcome Chemistry Scholar Award\, Camille Dreyfus Teacher-Scholar Award\, Eli Lilly Grantee Award and Zeneca Excellence in Chemistry Award. He has also served on ACS Division of Organic Chemistry as a Member-at-Large\, National Organic Symposium Executive Officer\, Councilor and Division Chair. He currently serves as one of the co-chairs of the highly acclaimed ACS-DOC Graduate Research Symposium. Additionally\, he is an Associate Editor for the Thieme journal\, Synthesis and the Editor-in- Chief for Organic Reactions.

SUMMARY:From Plant Scents to Perfumes
DESCRIPTION:Abstract\nPlant scents from flowers\, fruits\, leaves\, or tree barks are composed of complex mixtures of volatile organic compounds. People have used these fragrant mixtures since ancient times to produce lotions\, oils and perfumes. While contemporary perfumes and other scented products consist\, to a large extent\, of synthetic materials\, the inspiration for their components came mostly from natural compounds. In this presentation\, we’ll look at the compositions of some familiar plant scents\, including their functions\, and at typical structures of some of the compounds that compose them. From plant scents\, we’ll continue to fragrances and products that people today use in their daily lives\, such as shampoos\, soaps\, or expensive perfumes. This will include a look at synthetic compounds and mixtures that are used nowadays. \n       \nSpeaker bio\nMargareta (Greti) Séquin has a Ph. D. in organic chemistry from the University of Basel in Switzerland\, did postdoctoral work at Princeton University and at the Technical University of Munich\, and has taught organic chemistry at Dominican University and at San Francisco State University for more than thirty years. She has been giving many presentations on plant chemistry topics at botanical gardens and science centers. As an active member of the ACS California Section she participates in public events with hands-on activities on plant chemistry for general audiences. Because of her great interest in plants she has been a long-time docent at the Regional Parks Botanic Garden in Berkeley\, CA (more information about this park). Margareta is the author of the books The Chemistry of Plants: Perfumes\, Pigments\, and Poisons and The Chemistry of Plants and Insects: Plants\, Bugs\, and Molecules\, published by RSC\, Cambridge\, UK

SUMMARY:Chemistry in the Kitchen: Promoting Appreciation of Chemistry and Science
DESCRIPTION:Professor Richard Zare\, Stanford Chemistry Department \nAbstract:  For the past three years\, I have been offering a course to Stanford freshmen titled “Chemistry in the Kitchen.” Students are told the following before signing up for this course: This course examines the chemistry relevant to food and drink preparation\, both in homes and in restaurants\, which makes what we consume more pleasurable. Good cooking is more often considered an art rather than a science\, but a small bit of understanding goes a long way to make the preparation and consumption of food and drink more enjoyable. The intention is to have demonstrations and tastings as a part of every class meeting. We will examine some rather familiar items in this course: eggs\, dairy products\, meats\, breads\, vegetables\, pastries\, and carbonated beverages. We shall playfully explore the chemistry that turns food into meals. A high-school chemistry background is assumed; bring to class a good appetite and a healthy curiosity. \nMy goal has not been to make Iron Chefs or chemistry majors from those who take this course but instead to have the students learn how the science behind cooking can greatly increase their enjoyment of food. This lecture gives me the opportunity to tell you how this course came about and what aspects about the course make it a very popular course here at Stanford in which students leave the course with a new sense of the importance of chemistry in their daily lives. \nBio: Richard N. Zare is the Marguerite Blake Wilbur Professor of Natural Science. His website: www.stanford.edu/group/Zarelab contains more than you probably want to know about him and current research interests. He is particularly proud to have received the National Medal of Science in 1983 and the Presidential Award for Science\, Mathematics\, and Engineering Mentoring in 2012. He also received the Robert A. Welch Award in Chemistry in 1999\, the Wolf Prize in Chemistry in 2005\, the ACS Priestley Medal in 2010\, the King Faisal International Prize in Science in 2011\, and the Othmer Gold medal in 2017.
