## Abstract magnified image The condensation products of 2‐aminoethanol or 3‐aminopropanol (bearing an alkyl substituent on the carbon adjacent to the nitrogen) with substituted benzaldehydes proved to exist in CDCl~3~ at 300 K as threecomponent tautomeric mixtures of the diastereomeric five‐ or s
## Abstract A series of novel 2,3‐diaryl‐3,4‐dihydro‐__2H__‐1,3‐benzoxazines have been prepared in high yields from __o__‐arylaminomethylphenols and aromatic aldehydes in the presence of SnCl~4~ for the first time, and their fungicidal activities were investigated too. Some of the products showed g
