4-Benzylidene-2-aryl-4H-benzo[d][1,3] oxazines have been synthesized with high stereoselectivity and regioselectivities from 2-alkynylbenzamides in the presence of a catalytic amount of I2. In the reaction mechanism, iodine plays a key role in
Palladium-catalyzed highly regio-and stereoselective synthesis of 4-alkylidene-4 H -3,1-benzoxazines from N -Acyl-o -alkynylanilines

The highly regio-and stereoselective 6-exo-dig mode cyclization of N-acyl-o-alkynylanilines producing 4-alkylidene-3,1-benzoxazines occurred unpredictably by use of a proper catalyst [Pd(OAc)2] and an effective additive (acetic acid) under suit
