资源简介：
An enantioselective formal synthesis of the alkaloid (−)-cephalotaxine has been completed, using an alkylidene carbene 1,5-CH insertion reaction as a key step to construct the spiro[4.4]azanonane core D/E-ring system. A Heck-type cyclization was used to close the tetrahydroazepine C-ring and a selective epoxidation−rearrangement sequence was used to elaborate the E-ring.
