2-OXO-3-BUTENOATE ESTERS AS DIENOPHILES AND THEIR UTILITY IN A NOVEL SYNTHESIS OF PYRROLES

Jacobi, Peter A.,Cai, Guolin

, p. 1765 - 1768 (2007/10/02)

Trisubstituted pyrroles of type 8 have been prepared in a regiospecific fashion by a two step sequence involving Diels-Alder reaction of 2-oxo-3-butenoate esters 1 with 2-alkoxy-1,3-pentadiene derivatives 13, followed by ozonolysis and Paal-Knorr cyclization.
