Harnessing the Reactivity of Alkynes: Construction of Small Organic Moleculesof Pharmaceutical Interest Abstract: The simplicity, efficiency,and generality of reactions using alkyneshave led to its applications in the synthesis of a wide variety of small organic moleculesand natural products. Developing synthetic strategiesforsmall molecules in terms of selectivity, operational simplicity,functional group tolerance,and environmental sustainability isin constant [...]

Enabling Sustainable Chemistry with Precious Metal Catalysts through Hierarchical Design Professor Titel Jurca from University of Central Florida will present a seminar. Enabling Sustainable Chemistry with Precious Metal Catalysts through Hierarchical Design  Abstract: Due to inherent advantages relating to recoverability, temperature stability, and adaptability to industrial processes, heterogeneous catalysts dominate the industrial market share. Among those, palladium-based heterogeneous catalysts are critical enablers of numerous synthetic organic transformations. Examples range from C-C coupling reactions, C-H activations, to transfer and conventional hydrogenations. [...]

Cancelled Professor Audrey Lamb from the University of Texas at San Antonio will present a seminar. Evidence for the chemical mechanism of dihydroxybutanone phosphate (DHBP) synthase from riboflavin biosynthesis Abstract: RibB (3,4-dihydroxy-2-butanone 4-phosphate synthase) is a magnesium-dependent enzyme that excises the C4 of D-ribulose-5-phosphate (D-Ru5P) as formate. This chemistry forms the four-carbon substrate for RibE (lumazine synthase) that is incorporated into the xylene moiety of lumazine and ultimately the riboflavin isoalloxazine. The reaction was first identified in studies by Bacher [...]
