Synthesis of the Heterocyclic Compounds by Pschorr Cyclization. II. Syntheses of Substituted-6, 7-dihydrobenzo [a] quinolizinium Salts.

Abstract

The Pschorr reaction of 1- (2-amino-4, 5-methylenedioxyphenethyl) pyridinium (Va'), 1- (2-amino-4, 5-dimethoxyphenethyl) pyridinium (Vb) and 1- (2-amino-4, 5-dimethoxyphenethyl) picolinium (Vc) salts was carried out and the corresponding cyclized product was obtained respectively. 2-Amino-1- (3, 4-methylenedioxyphenethyl) pyridinium salt was prepared and its Pschorr reaction was investigated.
