A Journey through the Arabidopsis thaliana Genome: Discovering the Origins of Novel Triterpene Metabolites

Tuesday, June 3, 2014, 4:00 PM - 6:00 PM
Dorianne Castillo-Rivera, Doctoral Candidate

Plants produce a large variety of natural products, including over 20,000 different triterpenoids. Triterpenoid functions range from roles as membrane sterols and hormones in primary metabolism, to defense compounds in secondary metabolism. Beyond th more  »



Nonlinear terahertz spectroscopy and coherent control in solid, liquid, and gas phases

Friday, May 30, 2014, 4:00 PM - 5:00 PM
Keith Nelson, Professor of Chemistry, MIT

It has recently become possible to generate single-cycle or multiple-cycle electromagnetic fields in the 1-THz frequency range with electric field strengths in the 0.1-10 MV/cm range under various conditions. This is sufficient to induce nonlinear re more  »


Part I. Palladium-Catalyzed Alkyl C-H Activation Part II. Anion-Binding Catalysis for Asymmetric alpha-Amino Ester Synthesis

Wednesday, May 28, 2014, 4:00 PM - 5:00 PM
Masayuki Wasa, Postdoctoral Fellow, Harvard University

Transition metal-catalyzed activation/functionalization of C–H bonds and asymmetric organocatalysis are among the frontiers of modern organic chemistry. In the first section, Yu-Wasa Auxiliary-directed Pd-catalyzed activation of alkyl C(sp3)–H bonds more  »
