Abstract
2-( 1-Alkoxyalkyl)-4-alkylidene-4H-3,1-benzoxazines are conveniently prepared by the reaction of 1-(2-isocyanophenyl)ethanones or l-(2-isocyanophenyl)propan-l-ones with a vinyl ether, such as 2-methoxypropene or ethyl vinyl ether, in the presence of a catalytic amount of(±)-camphor-10-sulfonic acid.
