Abstract

A practical synthesis of 4,4-dimethyl-2-oxazolines on pyrrole was achieved via the cyclization of the corresponding amides, which were derived from the trichloroacetylpyrroles. The established conditions were applicable to pyrroles bearing a ketone or an ester moiety. In addition to pyrroles, the method could be extended to the synthesis of the indole derivative.
