Base-Promoted Azinium-N-imines and Thioamide Dimeric Annulation for the Tunable Synthesis of 1,2,4-Triazole and Polycyclic Indolylhydroquinoline Skeletons.

A base-promoted cycloaddition of azinium-N-imines with thioamides or indolin-2-thiones has been developed for the efficient construction of 1,2,4-triazole and polycyclic indolylhydroquinoline frameworks. This protocol features broad functional group…
