An acid-mediated 6-endo-trig cyclisation has been developed for the synthesis of trans-6-alkyl-2-methyl-4-oxopiperidines and used for the stereoselective preparation of quinolizidine alkaloid, (+)-myrtine and the piperidine alkaloid, (−)-solenopsin A.

AbstractBased on a higly diastereoselective Mannich reaction of N-(3,4-dimethoxybenzylidene) 2,3,4,6- tetra-O-pivaloyl-β -D-galactopyranosylamine 3 with the Danishefsky diene the quinolizidine alkaloid lasubin II was synthesized in enantiomerically pure form in six steps.
