A facile one-pot, microwave-assisted synthesis of some novel selenolopyrano[2,3-b]quinolines under microwave irradiation conditions

摘要

A series of some novel substituted selenolopyrano[2,3-b]quinolines 2a-c, 3a-c, and 4a-c were prepared from substituted 2-seleno-3-formyl-quinoliness 1a-c, which on reaction with ethyl acetoacetate, diethyl malonate, and ethyl cyanoacetate under microwave irradiation in the presence of piperidine gives the title compounds. The structure of newly synthesized compounds have been evaluated based on analytical, IR, 1H NMR, and mass spectral data.
