Stereoselective nucleophilic additions to trialkylsilyl-substituted acyclic acetals
摘要:
Regioselective and diastereoselective Mukaiyama-type aldol reactions of silyl-substituted mixed acyclic acetals provide the aldol products with 5:1 to 14:1 selectivity.

Reactions of α-epoxysilanes with cuprate reagents can be controlled to give β-silyl alcohols as major products. An oxidation, Grignard addition, and elimination sequence then provides alkenes with up to 98% de.
