摘要：

Reduction of (Z)-beta-butyltelluro-enones gives the corresponding gamma-hydroxy vinylic tellurides with retention of the double bond configuration. Reaction of gamma-hydroxy vinylic tellurides with 2 equiv of n-butyllithium produces 1,4-C,O-dianions, which on reaction with carbon dioxide give the corresponding butenolides. (c) 2007 Elsevier Ltd.
