Abstract

Variously substituted pyrroles 4 can easily be synthesized in two steps by reacting a primary or secondary amine and a ketene dithioacetal in a basic medium in moderate to good yield. Ketene dithioacetals 2 are readily prepared from acetylaceton or malononitrile, carbon disulfide, and methyl iodide.
