摘要：

(Z)-beta-Butyltellanyl alpha, beta-unsaturated carbonyl compounds were stereoselectively produced by hydrotelluration of alkynones or by an addition/elimination sequence from enol tosylates. The beta-butyltellanyl-enones were chemoselectively reduced with NaBH4/MeOH, NaBH(4)center dot CeCl(3)center dot 7H(2)O/MeOH and DIBAL-H systems to the corresponding allylic alcohols with retention of the Z stereochemistry.
