摘要:... A highly chemo- and stereoselective reaction is a Hantzsch-type domino process, involving the steps of initial nucleophilic C-addition or substitution and subsequent intramolecular nucleophilic addition without recyclyzation of imide cycle.

摘要:1-Aryl-substituted tetrahydrothieno[3,2-с]pyridines easily undergo domino reactions with activated alkynes, giving good yields of the corresponding tetrahydrothieno[2,3-d]azocines. The reactions of 1-methyl-substituted tetrahydrothieno[3,2-с]pyridine were more complicated.
