A CONNVENIENT METHOD FOR THE LARGE SCALE PREPARATION OF (E)-4-OXO-2-BUTENOIC ACID ETHYL ESTER

A one step synthesis of (E)-4-oxo-2-butenoic acid ethyl ester via the reaction of ethyl 2-ethoxy-2-hydroxyacetate and (formylmethylene)triphenylphosphorane is described.The method proceeds in good yeild on a molar scale.

SYNTHESE STEREOSELECTIVE DU DECADIENE-2(E), 4(Z)OATE D'ETHYLE. A PARTIR D'UN MONOACETAL DU GLYOXAL

The glyoxal monoacetal 2, now readily available in bulk quantity, is a very useful synthon for the dienes-1,3 synthesis, as illustrated in the stereoselective preparation of ethyl 2E,4Z-decadienoate using two Wittig-type olefination reactions.
