Abstract
The reaction of 2-isocyanatophenyl acetate with adamantyl and phenyl-containing amines gave the corresponding acetamides. Intermediate 2-isocyanatophenol formed in the course of the reaction undergoes intramolecular cyclization to 2-benzoxazolinone. These reactions proceed only with amines possessing basicity (pKb > 3.80).
