A one-pot synthesis of 2-aryl-3-alkyl/aryl-sulfonyl-(NH)-pyrroles from N-sulfonylpyrroles, developed for the first time, via palladium-catalyzed oxidative C-2 arylation followed by sulfonyl migration is described. The simple, easy access to the highly functionalized free-NH pyrroles secures opportunities for the preparation of compounds with promising biological activities in contemporary organic synthesis. The event of sulfonyl migration from pyrrole-N to C-3 is thermodynamically favored as revealed by density functional methods. The different plausible mechanisms for the migration of the sulfonyl group are also discussed.

A palladium-catalyzed regioselective C-2 arylation of 7-azaindoles, indoles, and pyrroles with arenes has been developed. This study unveils that a critical substrate dependent acid concentration is essential for achieving exclusive C-2 selectivity as wel

, p. 127 - 132 (2007/10/03)
A seven-stage synthesis of a pyrrole analogue of chloramphenicol (9) is described. The compound exhibits a significant antibacterial activity, over the 3% to 50% range of the chloramphenicol activity; over the 6% to 100% range of the thiamphenicol activity and florfenicol.
