α-succinimide-substituted allenoates were employed as phosphine acceptors in phosphine-catalyzed (4 + 2) annulation with 1,1-dicyanoalkenes. They served as C4 synthons in the annulation reaction under mild reaction conditions and produced hexahydroisoindole derivatives in moderate to high yields with good to excellent diastereoselectivities.
α-琥珀酰亚胺取代的丙二烯酸酯被用作膦催化的与1,1-二氰基烯烃的(4 + 2)环化反应中的膦受体。它们在温和的反应条件下作为环化反应中的C4合成子,以中等至高产率和良好至优异的非对映选择性生成六氢异吲哚衍生物。
