摘要

Reduction of (Z)-β-butyltelluro-enones gives the corresponding γ-hydroxy vinylic tellurides with retention of the double bond configuration. Reaction of γ-hydroxy vinylic tellurides with 2equiv of n-butyllithium produces 1, 4-C, O-dianions, which on reaction with carbon dioxide give the corresponding butenolides.
