説明
Abstract CsF induced 1,4-elimination of ammonium bromide 1a and the subsequent intramolecular cyclization of the resulting o-quinone methide N-alkenylimine 2a afforded benzo[e]-indolizidine 4a as a 4∼5 : 1 stereoisomeric mixture. Hydrogenation of 4a with 5% Rh on alumina gave tricyclic enaminoketones 5i and 5ii, of which stereoselective elaboration to gephyrotoxin 8 has already been established.
