The condensation of ethyl sarcosinate on 2- or 3-halogeno 3- or 2-formylbenzofuran, benzothiophene or benzoselenophene, and on the related 2H--3-benzoheterocyclanones is described.In the last instances the resulting compounds were formylated in the 2-position with subsequent cyclodehydration.After hydrolysis and decarboxylation, the 1-methylbenzothieno-, benzoselenopyrroles and the 1-methylbenzofuro, benzothieno- and benzoselenopyrroles were thus obtained.
