A new enantioselective total synthesis of phlegmarine-type Lycopodium alkaloid lycoposerramine-Z (1) has been accomplished, using one-pot chemoselective sequential additions of two different Grignard reagents to the bis-Weinreb-amide intermediate and an efficient construction of the fully fuctionalized cyclohexanone intermediate with a chiral phosphoric acid catalyzed enantioselective intramolecular Michael addition.
