摘要：

The syntheses of pyrrolidine alkaloids (-)-1 and (+)-3 were accomplished in 47% and 60% overall yield from 2-azido-2-deoxy-L-idonate 5, while piperidine alkaloids (-)-2 and (+)-4 were obtained in 51% acid 53% overall yield from the same starting material. Key step includes iodine promoted one-pot cyclization, and selective deprotection of isopropylidene and 9-phenylfluoren-9-yl (Pf) group.
