R. Caputo et al., CHEMISTRY OF ETHANEDIYL S,S-ACETALS .7. A STEREOSELECTIVE SYNTHESIS OF ALLYLIC ALCOHOLS WITH CIS-CONFIGURATED DOUBLE-BOND, Synthetic communications, 24(9), 1994, pp. 1223-1229
A new high yielding coupling reaction of C-2 monosubstituted 5,6-dihyd
ro-1,4-dithiins with aldehydes is reported. In this way allylic alcoho
ls having the cis-substituted double bond tied up by a sulfur-containi
ng ring can be readily prepared. Subsequent stereoselective sulfur rem
oval then affords allylic alcohols with cis-configurated double bond.
