3 test for phenol convinced the Author, perhaps a pupil of Ugo Schiff, to prefer the structure of a Schiff base for the condensation product that underwent hydrochloric acid hydrolysis, thus changing the first assignment consisting into the 1,3-diphenyl-2,3-dihydro-1H-naphtho[1,2-e][1,3]oxazine structure (see Scheme 2). The same iminic structure was then assigned to the diastereoisomeric derivatives obtained by reaction of the enantiomers of 1-(α-aminobenzyl)-2-naphthol (1) with racemic aldehydes resolved by Betti
