Synthesis and Reactions of Methyl 8-Aryl-6-Methyl-9-Oxo-8,9-Dihydro-5H-Dibenzo[4,5:6,7]Cyclohepta[1,2-B]Pyridine-7-Carboxylates

Abstract

A method for the synthesis of methyl 4-aryl-6-methyl-9-oxo-8,9-dihydro-5H-dibenzo[4,5:6,7]cyclohepta[1,2-b]pyridine-7-carboxylates from 6-arylidenedibenzo[a,c][7]annulene- 5,7(6H)-diones and methyl 3-aminocrotonate has been developed. The alkylation, oxidation, and reduction of the obtained annulated dihydropyridines were studied
