A novel domino reaction of (2-iminoaryl)divinyl ketones with nitromethane was developed for the efficient synthesis of hexahydrophenanthridin-9(5H)-ones. The reaction proceeded smoothly from readily available starting materials under mild reaction conditions to construct three new bonds and two rings with high diastereoselectivities in good to excellent yields in a single step. A mechanism is proposed, involving a stepwise double Michael addition/aza-Henry reaction cascade, and in this transformation, nitromethane acts as a trinucleophile.
发展了一种（2-亚氨基芳基）二乙烯基酮与硝基甲烷的新型级联反应，用于高效合成六氢菲并[9,5-h]异喹啉-9(5H)-酮。该反应从易得的起始原料在温和的反应条件下顺利进行，以高非对映选择性和良好至优秀的收率一步构建了三个新键和两个环。提出了一个涉及分步双迈克尔加成/氮杂 Henry 反应级联的机理，在这种转化中，硝基甲烷作为三亲核试剂。
