Efficient, microwave-assisted intramolecular 1,3-dipolar cycloadditions of oximes and N-methylnitrones derived from o-alkenylmethoxy-acetophenones

Singh, Surinderjit,Ishar,Singh, Gajendra,Singh, Rajinder

, p. 260 - 265 (2007/10/03)

Contrary to literature reports, the o-allyloxy- and crotyloxy-acetophenone- oximes (2a, 2b) are transformed to nitrones, which undergo regio- and stereoselective intramolecular 1,3-dipolar cycloadditions, both on microwave heating under solvent free condi
