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.
