By using a quantum-chemical approach, B2PLYP-D2/6-311+G**//B3LYP/6-31+G*, we have carried out detailed study of the assembly 1-pyrrolines from N-benzyl-1-phenylmethanimine and phenylacetylene in superbasic medium KOtBu/dimethyl sulfoxide (DMSO). In this way, considered, both theoretically experimentally, mechanisms through concerted stepwise nucleophilic cycloaddition addressed side processes accompanying assembly. It is found that via kinetically more favorable than cycloaddition. At same time, reaction C-vinylation aldimine with occurs similar activation energy as leads to formation 2-aza-1,4-pentadiene. The anion 2-aza-1,4-pentadiene an intermediate for leading triarylpyridines 1,3-diarylpropan-1-ones. Triarylpyridines are formed next molecule 2-aza-1,4-pentadiene, while 1,3-diarylpropan-1-ones result hydrolysis 2-aza-1,4-pentadienes. mild conditions (60 °C, 15 min) relate complexes KOtBu/DMSO medium, where readily accessible attack by molecule.

This study developed an eco-friendly method to synthesize 3-arylisoquinoline from 2-alkynylbenzaldehydes using Nafion® NR50 as acidic catalyst and hexamethyldisilazane (HMDS) a nitrogen source. The reaction proceeded via 6-exo-dig cyclization under microwave irradiation, giving the corresponding isoquinolines in excellent yields. advantages of this protocol include: (1) use recyclable acid catalysts, (2) transition-metal-free catalysis, (3) effective formation target product. These features make methodology promising approach for sustainable efficient synthesis 3-arylisoquinoline. Some structures were also confirmed by single-crystal X-ray diffraction analysis.
