摘要:
Cephalotine A, a recently isolated Cephalotaxus alkaloid,was firstsynthesized enantioselectively through three critical reactions. SmI2 -mediated radical cyclization of lactone and aldehyde toforge the final ring system, Chang's iridium-catalyzed C-Hamidation to construct pyrrolidone stereoselectively, and Carreria'sdual Ir/amine catalyzed allylation to install the vicinal tertiarystereocenters.
