1-(Phenylsulfonyl)-2-(trimethylsilyl)ethane. A valuable intermediate for synthesis of olefins, allyltrimethylsilanes, .beta.-trimethylsilyl ketones, vinyl sulfones, 2-(phenylsulfonyl)allyl alcohols, and varied trimethylsilyl derivatives
The reaction of β-(trimethylsilyl)alkyl phenyl sulfones with oxiranes. A method for stereocontrolled synthesis of homoallylic alcohols
摘要:
The reaction of beta-trimethylsilylalkyl sulfones (4a-4b) with oxirane derivatives (5a - 5d, 9) followed by treatment of the immediate adducts with sodium hydride, affords O-trimethylsilyl homoallylic alcohols (7a - 7e, 11), mainly (Z) isomers.
