Speaker: Professor Yu Zhixiang, Peking University

Where: Versatile Vinylcyclopropanes in Synthesizing Ring Compounds

Under transition metal catalysis, vinylcycloropanes can act as either five-carbon units or three-carbon units to undergo various [m+n], [m+n+o] cycloadditions with other carbon units such as alkenes, alkynes, CO, demonstrating the versatility of vinylcyclopropanes in synthesizing various ring compounds. In this talk, several Rh-catalyzed cycloaddition reactions of vinylcycloropanes for the synthesis of ring compounds developed in the Yu group, such as the [5+2+1], [7+1], benzo/[7+1], [3+2], [3+2+1], formal [5+1]/[2+2+1], [5+1] reactions, will be presented. Also the application of these cycloadditions in natural product synthesis will be briefly introduced.
