Diversity-Oriented Stereoselective Synthesis of β,γ-Disubstituted tert-Homoallylic Alcohols
摘要:
The successive treatment of beta-(trimethylsilyl)allyl phenyl sulfides with titanocene(II)-1-butene complex and ketones produced tertiary gamma-(trimethylsilyl)homoallylic alcohols with good anti-selectivity, which reacted with a variety of organic halides in the presence of copper(I) tert-butoxide to afford the cross-coupling products, gamma-substituted homoallylic alcohols.
