A highly efficient one-pot synthesis of enantiomerically enriched 2-aryl-2,3-dihydroquinolin-4(1H)-ones has been carried out for the first time using per-6-ABCD as a supramolecular host, chiral base catalyst, and a reusable promoter to give the corresponding scaffold with high yield (up to 99%) and enantiomeric excess (up to 99%). The catalyst is recovered and reused without loss in its activity.
首次使用超分子主体 per-6-ABCD 作为手性碱催化剂和可重复使用的促进剂,高效一锅法合成了对映体富集的 2-芳基-2,3-二氢喹啉-4(1H)-酮,以高产率(高达 99%)和对映体过量(高达 99%)得到相应的支架。催化剂回收后可重复使用,活性无损失。
