, p. 658 - 663 (2007/10/02)
A synthesis of 1H-pyrroles is described starting with pyridine analogues of chalcones and involving the reacxtion of acetic anhydride with 1-pyrroline-1-oxides.Another route leads from 1-pyrrolines to 2H-pyrroles via bromination with N-bromosuccinimide and subsequent dehydrobromination in dimethylformamide.
