Abstract
Controlled reduction of N-methyl-3-ethylpyridinium iodide afforded the corresponding 1,2-dihydropyridine which was stabilised by complexation to give 1,2- and 1,6-dihydro-3-ethyl-N-methylpyridinetricarbonylchromium(0). These stable, isomeric complexes were interrelated by thermal equilibration. Analogous sequences with more complex, alkaloid derivatives enabled formation, and stabilisation by complexation, of 1,2- and 1,6-dihydropyridines in the presence of other functions such as the indole unit and ester groups.This publication has 1 reference indexed in Scilit:
