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.

Key Steps

The C24–C40 fragment of (−)-pulvomycin was prepared in enantiomerically pure form using a concise synthesis method (15 linear steps from d-fucose, 6.8% overall yield) featuring a diastereoselective addition to an aldehyde, a β-selective glycosylation and a Stille cross-coupling as the key steps.
