Mild and simple catalytic systems consisting of molybdenum(VI) dichloride dioxide [MoO2Cl2] as a catalyst and a phosphine as reductant have been developed for the stereospecific deoxygenation of epoxides to alkenes. The reactions using 1,2-bis(diphenylphosphino)ethane (dppe) and triphenylphosphine (PPh3) proceed with retention and inversion of stereochemistry, respectively. The mild reaction tolerates the presence of various functional groups and affords stereodefined substituted olefins in good yields. (Figure presented.).
Simple protocol for enhanced (E)-selectivity in Julia-Kocienski reaction

supporting information; experimental part, p. 2348 - 2352 (2011/05/16)
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
THREO SELECTIVE CROSS ALDOL CONDENSATION WITH THIOAMIDE ENOLATES GENERATED BY A MICHAEL ADDITION OF ORGANOMETALLICS TO UNSATURATED THIOAMIDES
