Abstract

A mechanism is proposed for the formation of 4,4-diphenyl-1,2-dihydro-4H-3,1-benzoxazines, which has been proved by introducing a 17O/18O isotopic label into the starting 2-aminophenyldiphenylmethanols and carbonyl compounds. 17O NMR and mass spectrometry show that the 3,1-benzoxazine ring contains the oxygen atom from the alcohol group in the starting 2-aminophenyldiphenylmethanol.
