Rojo,Garcia,Carretero
, p. 9787 - 9800 (2007/10/02)
A stereoselective route for the preparation of cis and trans disubstituted (and trisubstituted) γ-lactones starting from the readily available α-(phenylsulfonyl)-α,β-unsaturated esters 3 or α-(phenylsulfonyl)butenolides 4 is described. This method is base

Synthesis and conjugate additions to (E)-γ-alkoxy-α-substituted-α,β-unsaturated sulfones

(E)-γ-hydroxy-α,β-unsaturated sulfones have been readily functionalized at α-position via protection of hydroxyl group, metalation with n-BuLi and subsequent reaction with electrophiles. The conjugate addition of organolithiums to (E)-γ-methoxymethoxy-α-trimethylsilyl-α,β-unsaturated phenyl sulfones in Et2O is highly syn-stereoselective
