Synthesis of 1,4-dihydro-2H-3,1-benzoxazin-2-ones by hydriodic acid mediated cyclization of t-butyl 2-vinylphenylcarbamates

A two-step facile synthesis of 4,4-disubstituted 1,4-dihydro-2H-3,1- benzoxazin-2-ones starting from α-substituted 2-aminostyrenes is described. The method involves the hydriodic acid mediated cyclization of t-butyl 2-vinylphenylcarbamate derivatives, whi
