Reaction of phosgene with the tricycle related to the minor base of phenylalanine transfer ribonucleic acids

1-Benzylwye (8) underwent electrophilic substitution at the 7-position in the presence of phosgene and pyridine in tetrahydrofuran (THF) to afford the 1,4-dihydropyridines (11, 10, and 14) together with the carboxylic acid 6 and its methyl ester 2 after s

New reactions of phosgene with tertiary amines

1-Benzylwye (3) underwent substitution at the 7-position in the presence of COCl2 and pyridine in THF to afford various products depending upon the post-treatment through 1,4-dihydropyridine (7) and carboxylic acid derivative (8). When Et3N was used instead of pyridine, it reacted with COCl2 to provide two enamines (18 and 19), together with diethylcarbamyl chloride (20), after treatment of the reaction mixture with MeOH.
