The novel 4-formyl-2,1-benzisoxazole and 7-formyl-2,1-benzisoxazole were prepared for conversion via the Hantzsch synthesis to 1,4-dihydropyridines. The 4-formyl derivative underwent efficient cyclization to the dihydropyridine while analogous reaction of the 7-formyl compound has proven problematic.
制备了新型的4-甲酰基-2,1-苯并恶唑和7-甲酰基-2,1-苯并恶唑,用于通过汉茨化学合成法转化为1,4-二氢吡啶。4-甲酰基衍生物有效地环化成二氢吡啶,而已证明7-甲酰基化合物的类似反应是有问题的。
