)-1-arylprop-2-en-1-ones with anilines and ninhydrin in an equimolar ratio upon grinding in the presence of acetic acid (0.1 ml per mmol of reactants) afforded highly functionalized dihydroindeno[1,2-b]pyrroles regio- and stereoselectively in good yields. This protocol has advantages such as solvent-free reactions under grinding, ambient temperature, short reaction times, simple work-up avoiding chromatographic
(E)-3-(二甲基氨基)-1-芳基丙-2-烯-1-酮与苯胺和茚三酮的等摩尔比,在乙酸存在下研磨时容易进行的三组分多米诺反应(0.1 ml / mmol反应物)以良好的收率选择性和高度选择性地提供了高度官能化的二氢茚并[1,2- b ]吡咯。该方案具有诸如在研磨条件下无溶剂反应,环境温度,较短的反应时间,无需色谱纯化即可进行简单后处理等优点,并具有出色的收率。
