摘要

Abstract New 1-(1-aminoalkyl)-2-naphthols 8–11 have been synthesised by the condensation of 2-naphthol with aliphaticaldehydes in the presence of ammonia, followed by acidic hydrolysis. The condensation of 7–11 with substitutedbenzaldehydes after microwave irradiation led to1-alkyl-3-aryl-2, 3-dihydro-1H-naphth [1, 2-e][1, 3] oxazines, which proved to be three-component (r t-or c) tautomeric mixtures in CDCl 3 at 300 K. The ...
