Abstract

The stereospecific reduction of EE 2-benzenesulfonyl-1, 3-dienes to ZE 1, 3-dienes with Grignard reagents under transition metal catalysis ie described, Hydrogenolysis of the sulfonyl moiety of 2-benzenesulfonyl-1, 4-dienes to ZE 1, 4-dienes with sodium dithionite ie reported. These techniques have been applied to the stereoselective synthesis of (7E, 9Z) dodecadienyl acetate 3d,(9Z, 11E) tetradecadienyl acetate 3e and (9Z, 12E) ...
