Three-component synthesis of 5,6-dihydropyrrolo[2,1-a]isoquinolines from 1-aroyl-3,4-dihydroisoquinolines, electron-deficient alkynes and NH-acids

The three-component domino reaction involving 1-aroyl-3,4-dihydroisoquinolines, terminal alkynes, and cyclic NH-acids is a new method for the synthesis of 5,6-dihydropyrrolo[2,1-a]isoquinolines containing in position 3, cyclic nitrogen-containing fragments. The transformation is performed under microwave irra-diation in dry acetonitrile at 130 degrees C.CO 2022 Elsevier Ltd. All rights reserved.
