Abstract :
(Z)-β-Butyltellanyl α,β-unsaturated carbonyl compounds were stereoselectively produced by hydrotelluration of alkynones or by an addition/elimination sequence from enol tosylates. The β-butyltellanyl-enones were chemoselectively reduced with NaBH4/MeOH, NaBH4·CeCl3·7H2O/MeOH and DIBAL-H systems to the corresponding allylic alcohols with retention of the Z stereochemistry.
