Abstract

Alkyl 2‐(2‐benzoyl‐2‐ethoxycarbonyl‐1‐ethenyl)amino‐3‐dimethylaminopropenoates 4a,b were prepared. They react with C‐nucleophiles such a 2‐pyridinylacetonitrile 5 and methyl‐2‐quinolinylacetate 8, cyclohexane‐1,3‐dione 10 and its derivatives 12 and 14, resorcinol derivative 16, 2‐naphtol 18, 2‐pyranone derivatives 20 and 22, and 4‐hydroxypyridin‐2(1__H__)‐one 24, to form substituted amino derivatives of quinolizine 6, benzo[c]quinolizine 9, tetrahydrobenzopyran‐2‐one 11, 13, 15, naphto[2,1‐b]pyran‐3‐one 19, pyranopyranones 21, 23, and pyrano[3,2‐c]pyridine 25.
