As reported by Scheidt and Bode in 2005, sterically nonencumbered alpha,beta-enals are readily converted to saturated esters in the presence of alcohols and N-heterocyclic carbene catalysts, e.g., benzimidazolylidenes or triazolylidenes. However, substituents at the alpha- or beta-position of the alpha,beta-enal substrate are typically not tolerated, thus severely limiting the substrate spectrum. On the basis of our earlier mechanistic studies, a set of N-Mes- or N-Dipp-substituted 1,2,4-triazolium salts were synthesized and evaluated as (pre)catalysts in the redox esterification of various alpha- or beta-substituted enals. In particular the 1,4-bis-Mes/Dipp-1,2,4-triazolylidenes overcome the above limitations and efficiently catalyze the redox esterification of a whole series of alpha/beta-substituted enals hitherto not amenable to NHC-catalyzed transformations. The synthetic value of 1,4-bis-Mes/Dipp-1,2,4-triazolylidenes is further demonstrated by the one-step bicyclization of 10-oxocitral to (racemic) nepetalactone in diastereomerically pure form.

3-(Piperidin-4-yl)-6,7-dihydro-5H-pyrrolo[2,1-c][1,2,4]triazole was synthesized through a four-step process including etherification, hydrazonation, cyclization, and reduction with an overall yield of 39%. The final product was characterized by 1H NMR and ESI-MS/MS. The molecular structures of benzyl (Z)-4-(2-(pyrrolidin-2-ylidene)hydrazine-1-carbonyl)piperidine-1-carboxylate and related compounds were analyzed using DFT calculations at the B3LYP/6-311+G(d,p) level of theory. The results indicated a higher stability of the hydrazone tautomers.

Highly beta-regioselective Friedel-Crafts aminoalkylation of pyrroles with cyclic perfluoroalkylated imines

A Friedel-Crafts-type alkylation reaction was studied between various pyrroles and alpha-polyfluoroalkylated cyclic imines that were activated by Lewis acids. The reaction proceeded under mild conditions and provided a high yielding synthesis of alpha-CF3-substituted pyrrolidines and piperidines as well as seven-membered analogues that contained a pyrrole ring. The unpredictably high beta-selectivity for the aminoalkylation of both 1H-pyrrole and N-substituted pyrrole was observed as a result of a thermodynamically-controlled electrophilic substitution reaction. The computational data are in full agreement with the experimental results, which confirmed the observed regioselectivity as a result of the lower energy of the beta-substituted pyrroles that contain alpha-trifluoromethyl-substituted pyrrolidine, piperidine, and azepane rings. Trifluoromethyl-substituted cyclic imines were activated by various Lewis acids and underwent a reaction with pyrrole derivatives. An unpredictable beta-selectivity was observed. The regioselectivity of the aminoalkylation was explained by computation data, which also confirmed the isomerization of the alpha isomer into the beta isomer. Copyright
