摘要:
An efficient three component, four-centered A3 coupling strategy has been developed for the synthesis of a novel series of 1-arylethynyl-tetrahydro-beta-carboline derivatives in good yields with high selectivity. This method is also useful for the preparation of 1-arylethynyl tetrahydroisoquinolines, which can be used for the synthesis of biologically active molecules such as homolaudanosine, dysoxyline, methopo-line and almorexant. The use of a readily available ZnCl2/Et3N reagent system makes this method simple, convenient and practical. (C) 2017 Elsevier Ltd. All rights reserved.
