Several 2–amino‐6‐(1‐aryl‐5‐methyl‐1H‐1,2,3‐triazol‐4‐yl)‐4‐phenylpyridine‐3‐carbonitrile have been synthesized by Tandem Michael addition/imino‐nitrile cyclization and the structures of these compounds were established by MS, IR, CHN, and 1H NMR spectral data. The crystal structure of 2‐amino‐6‐[1‐(4‐methoxyphenyl)‐5‐methyl‐1H‐1,2,3‐triazol‐4‐yl]‐4‐phenylpyridine‐3‐carbonitrile was established by

thionylation – hetero-Diels–Alder domino reaction using α,β-unsaturated ketones with 1,2,3-triazole substituents, namely, 3-[2-(allyloxy)phenyl]-1-(1-aryl-5-methyl-1H-1,2,3-triazol-4-yl)-prop-2-en-1-ones, leading to 3,4-dihydro-2Н-thiopyranes and thiopyrano[3,4-с]chromenones. Variants of intra- and intermolecular cycloaddition were studied, as well the stereo- and regioselectivity of such reactions was assessed
