A short and efficient Julia-Kocienski olefination protocol, based upon the use of chelating agents (18-crown-6 or TDA-1 for K+; 12-crown-4 or HMPA for Li+), was developed. This protocol enhances the (E)-selectivity of the reaction an
DBP YLDES: WITTIG REAGENTS FOR SYNTHESIS OF E-ALKENES FROM ALDEHYDES

Phosphorus yldes based on the dibenzophosphole (DPP) ring system convert aldehydes into trans-disubstituted oxaphosphetanes with good to excellent selectivity.Decomposition at 70-110 deg C affords alkenes with E:Z rations from 6:1 to > 100:1.
