摘要
From available hydroxy-aldehyde 6, propargylic derivative 8 was prepared and treated with Bu(3)SnH to give in 95% yield the bicyclic vinyl stannane 10. After 10 was converted into the diol 15, this latter was oxidized with the Dess-Martin reagent into the dialdehyde 4. Compound 4 was then submitted to a pinacolic coupling reaction leading to the bicyclic cis-diol 3 in a stereospecific manner.
