Abstract
... DIRECT SYNTHESIS OF Z-UNSATURATED ESTERS. A USEFUL MODIFICATION OF THE HORNER-EMMONS OLEFINATION. W. Clark Still and Cesare Gennari Department of Chemistry Columbia University New York, New York 10027 USA Summary ... All of the effective bases found in our study seem to meet this requirement and we expect that other conditions 6 can be devised accordingly and used with reagents like 2 and 3 for efficient Z olefination. ...
