Article abstract of DOI:10.1016/S0040-4039(00)74324-3

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.
