Macchindra Tambe Somnath Gholap, Umesh Deshmukh

An efficient synthesis of some novel coumarin derivatives via 1, 4- Michael addition of indole to coumarin chalcones catalyzed by cellulose sulphonic acid (CSA) under solvent free conditions is described. The corresponding Michael addition products were obtained in good to excellent yield. The synthesized compounds were screened for their antibacterial activity against E. coli, S. aureus and an...

6-Carbethoxy-5-(3'-bromophenyl)-3-aryl-2-cyclohexenones 2a-j were obtained from the1-Aryl-3-(3'-bromophenyl)-2-propene-1-ones 1a-j by Micheal addition of ethyl acetoacetate, followed by internal Claisen condensation. Reaction of 2a-j with hydrazine hydrate afforded the corresponding 6-Aryl-4-(3'-bromophenyl)-3-oxo-2,3a,4,5-tetrahydro-2H-indazoles 3a-j. The structures of newly synthesized compou...

Kurosh Rad-Moghadam Shaghayegh Gholizadeh

An efficient and convenient protocol for synthesis of 3-hydroxy-3-indolyl-2-oxindoles and 3,3-diindolyl-2-oxindoles is presented here. The syntheses were achieved selectively under catalysis of LiClO4 whereby the products were obtained purely.
