Synthesis and tautomerism of 1-substituted 3,3-dialkyl-3,4-dihydroisoquinolines
A number of ethyl esters of 3,3-dialkyl-3,4-dihydroisoquinoline-Δ1(2H), α-α- alkylacetic acids have been synthesized. The effect of replacement of α-hydrogen by alkyl radicals on the azomethine-enamine tautomeric equilibrium was shown.
