Reactions of 2-Hydroxybenzonitrile with Isocyanates

Triethylamine catalyzes the reaction of 2-hydroxybenzonitrile (1) with arylisocyanates to form the corresponding carbamates 2a-c, as well as the cyclization of the latter compounds to either 4--3-aryl-2H-1,3-benzoxazin-2-ones 4a-c, or 4-arylamino-2H-1,3-benzoxazin-2-ones 7a-c, depending on the reaction temperature.Under analogous conditions, the carbamates obtained from 1 and 2-chloroethyl isocyanate, 3-chloropropyl isocyanate and ethyl isocyanatoacetate undergo a double cyclization yielding imidazo- and pyrimidobenzoxazinones 13a, b, 17.Upon heating in phenyl ether, compounds 7a-c, rearrange to 2-(2-hydroxyphenyl)-4(3H)-quinazolinones 10a-c.
