Microwave-assisted synthesis of 3′-indolyl substituted 4H-chromenes catalyzed by DMAP and their antimicrobial activity
摘要:
A new series of indole-based chromene derivatives 4a-4p has been synthesized by one pot cyclocondensation reaction of 2-phenyl-1H-indole-3-carbaldehyde 1a-1h; malononitrile 2; and 1,3-cyclohexanedione/dimedone 3a/b under microwave irradiation catalyzed by an organocatalyst 4-(N,N-dimethylamino) pyridine. Easy experimental procedure, high yield, selectivity, and shorter reaction time are the imperative features of this method. All the compounds were screened against a representative panel of bacteria and fungi. Some of the compounds are found to be equipotent or more potent than that of standard drugs as evident from SAR study.

green, and efficient method of synthesis of pyran fused indolyl and 1,3-dicarbonyl analogs has been carried out under the conventional and also solvent-free conditions involving MW irradiation. The structures of products have been confirmed by spectral data. All products have been tested for DNA cleavage and in vitro cytotoxicity against three tumor cell lines. Some products are characterized by high
