The morpholine promoted three-component reaction of N-alkylpiperidinone, indane-1,3-dione and 2-arylideneindane-1,3-dione in ethanol at room temperature resulted in the (1H-1,5-methanoindeno[1,2-d]azocin-12-ylidene)-1H-indene-1,3(2H)-dione derivatives in good yields and with exo-configuration. Under similar conditions, the reaction of N-alkylpiperidinone with 2-arylideneindane-1,3-dione afforded 7H-1
在室温下,吗啉在乙醇中促进了N-烷基哌啶酮,茚满-1,3-二酮和2-芳撑茚满-1,3-二酮的三组分反应,生成了(1 H -1,5-甲亚胺[1,2] - d ]吖辛因-12-亚基)-1- ħ -茚-1,3(2 ħ)以良好的收率和与-二酮衍生物外-构型。在相似的条件下,N-烷基哌啶酮与2-芳基茚满-1,3-二酮的反应提供了7 H -1,5-甲亚甲基[1,2 - d ]偶氮电影-7,12-二酮,内含-配置。据信多米诺反应是用多米诺Knoevenagel缩合,迈克尔加成和醛醇缩合反应进行的。
