Base-catalysed addition of phenylacetonitrile to 1-methyl-3-cyano-1, 6-dihydropyridine (II) is shown to give α-[1-methyl-3-cyano-1.4.5.6-tetrahydro-pyridyl-(4)]-phenylacetonitrile (VI). The structure of VI has been proved by its reduction to the saturated dicyano compound VIII, which has also been synthesized by the MICHAEL- type addition of phenylacetonitrile to 1-methyl-3-cyano-l.2.5.6-tetrahydro-pyridine
已显示碱催化将
苯乙腈加至1-甲基-3-
氰基-1,6-
二氢吡啶(II)中,得到α-[1-甲基-3-
氰基-1.4.5.6-四氢
吡啶基-(4)]-苯基
乙腈(VI)。通过将VI还原成饱和的二
氰基化合物VIII来证明VI的结构,该化合物也通过将
苯乙腈向1-甲基-3-
氰基-1.2.5.6-四氢
吡啶(IX)进行MICHAEL型加成而合成。
