The synthesis of beta-phenylethanolamine analogs in which the phenyl ring is replaced by cyclohexyl, cyclohexen-4-yl, cyclooctyl, cyclooctenyl, cycloocta-1,3-dien-2-yl, cycloocta-1,5-dienyl, and cyclooctatetraenyl was accompanied by conversion of the corresponding aldehydes to the cyanohydrins followed by reduction with lithium aluminum hydride. A preparatively useful synthesis of 1-formylcyclooctatetraene
其中苯环被环己基,环己烯-4-基,环辛基,环辛烯基,环辛基-1,3-二烯-2-基,环辛基-1,5-二烯基和环辛酸酯基取代的β-苯基乙醇胺类似物的合成伴随将相应的醛转化为氰醇,然后用氢化铝锂还原。描述了一种利用丙炔酸甲酯与苯的光环加成反应,然后还原成醇并用MnO2氧化的1-甲酰基环辛酸酯的合成方法。所有化合物,作为它们的盐酸盐,对大鼠输精管表现出间接的肾上腺素能活性。在重新固定的大鼠输精管上,所有化合物均增强了外源去甲肾上腺素的作用。结果与以下结论一致:环部分越饱和,
