A series of new 2,3-disubstituted-3,4-dihydro-2H-1,3-benzoxazines were prepared in moderate to excellent yields by aza-acetalizations of aromatic aldehydes with 2-(N-substituted aminomethyl)phenols in the presence of TMSCl. Their structures were confirmed by IR, 1H-NMR, 13C-NMR, MS and elemental analysis. The fungicidal activities of the target compounds were preliminarily evaluated, and some compounds exhibited good activity against Rhizoctonia solani.
一系列新的2,3-二取代-3,4-二氢-2H-1,3-苯并噁嗪在TMSCl的存在下通过芳香醛与2-(N-取代氨基甲基)酚的氮杂乙缩合反应以中等到优良的产率制备。这些化合物的结构通过红外光谱、1H-NMR、13C-NMR、质谱和元素分析得到了确认。对目标化合物的杀真菌活性进行了初步评估,其中一些化合物对根腐菌Rhizoctonia solani展现了良好的活性。
