New cyclisation reaction of aryl-lithium species; X-ray crystal structure of (2,3-dihydro-3-benzofuryl)acetanilide
Abstract
Direct metallation of 3-allyloxybenzanilides gave the 2-lithioderivatives, which underwent a cyclisation process to yield (2,3-dihydrobenzofuryl)acetanilides; the structure of (2,3-dihydro-3-benzofuryl)acetanilide has been determined by X-ray crystallography.
