摘要：
D-1,6-Diepicastanospemine has been prepared via reaction of an allylstannane with the arabinose derivative 1a. This reaction was almost 100 % stereoselective, but the corresponding allylations of aldehydes 1b - d gave mixtures of isomers. Variable stereodifferentiation in these reactions can be attributed to the influence of the distal (gamma) chiral center.
