nyl]benzamide to give 2-phenylarylspiro[3,1-benz-oxazine-4,1'-cyclopentane] was carried out in the presence of DCl. Analysis of the electron impact mass spectra of this benzoxazine and its deuterated analogs showed initial formation of a monodeuterated product. The contributions of polydeuterated benzoxazines increase as the reaction progresses.
