Reactions of cyano olefins with (i) enamino imides afforded novel pyrrolo[3,4‐b]pyridines; (ii) enamino esters afforded new 1,4‐dihydropyridines; and (iii) bisenamino ester afforded new 1,1′‐(1,4‐phenylene)bis(1,4‐dihydropyridine). The new derivatives are planned as suggested drug candidates.
氰基烯烃与(i)烯氨基酰亚胺的反应提供了新型的吡咯并[3,4- b ]吡啶;(ii)烯氨基酯提供了新的1,4-二氢吡啶; (iii)联氨基酯提供了新的1,1'-(1,4-亚苯基)双(1,4-二氢吡啶)。新的衍生物计划作为候选药物。
