    Features of a multicomponent biginelli reaction involving 3-oxobutanoyl-containing podands, aromatic aldehydes, and 1,2,4-triazol-3-amine / E. S. Filatova, O. V. Fedorova, K. A. Chistyakov [et al.] // Chemistry of heterocyclic compounds. - 2020. - Vol. 56, № 1. - P88-91

DIHYDROPYRIMIDINE -- MONOSUBSTITUTED PODAND -- PODAND -- TRIAZOLO[1,5-А]PYRIMIDINE -- TRIAZOLO[4,3-А]PYRIMIDINE -- TUBERCULOSTATIC ACTIVITY
Аннотация: [Figure not available: see fulltext.] A reaction of 3-oxobutanoyl-containing podands with thiophene-2-carbaldehyde (or benzaldehyde) and 3-amino-1,2,4-triazole gave podands featuring a 4,7-dihydro[1,2,4]triazolo[1,5-а]pyrimidine motif. It was established that the process was accompanied by the formation of [4,3-а]-isomers, which occurred in a slight excess during the synthesis of a podand containing a phenyl group at position 7 and, on the other hand, were observed as the minor products during the synthesis of podands bearing a thiophen-2-yl substituent. Trace amounts of monosubstituted podands were also detected, containing a free hydroxy group along with the triazolodihydropyrimidine pharmacophore.

    Oxidative aromatization of 4,7-dihydro-6-nitroazolo[1,5-a] pyrimidines: synthetic possibilities and limitations, mechanism of destruction, and the theoretical and experimental substantiation / D.

AZOLO[1,5-A]PYRIMIDINES -- NITRO-SYNTHONS -- OXIDATION -- OXIDATIVE DESTRUCTION -- SYNTHESIS OF HETEROCYCLES -- NITRO COMPOUNDS
Аннотация: The reaction tolerance of the multicomponent process between 3-aminoazoles, 1-morpholino-2-nitroalkenes, and aldehydes was studied. The main patterns of this reaction have been established. Conditions for the oxidation of 4,7-dihydro-6-nitroazolo[1,5-a]pyrimidines were selected. Previous claims that the 4,7-dihydro-6-nitroazolo[1,5-a]pyrimidines could not be aromatised have now been refuted. Compounds with an electron-donor substituent at position seven undergo decomposition during oxidation. The phenomenon was explained based on experimental data, electro-chemical experiment, and quantum-chemical calculation. The mechanism of oxidative degradation has been proposed.

    Iron(III)-catalyzed multicomponent synthesis of highly substituted pyrroles under ball-milling conditions / A. Mukherjee, S. Al-Ghezi Basim, G. V. Zyryanov, O. N. Chupakhin // Современные синтетические методологии для создания лекарственных препаратов и функциональных материалов" (MOSM 2021): V международная конференция: сборник тезисов. - Екатеринбург, 2021. - C. PR-186

Аннотация: Nowadays, green chemistry plays an important role for environment. In this context, development of solvent-free ball milling or a grinding approach has attracted considerable interest in organic synthesis.1 Hence, carrying out a reaction under solvent-free conditions and at room temperature is an effective approach to eliminate the use of volatile organic compounds and to obtain the greenness in the process. On the other hands, pyrroles are the small aromatic, nitrogen-containing heterocyclic compounds present in many natural products.2 Pyrrole molecules show important biological relevance such as porphyrins, bile pigments, and coenzymes and are known to exhibit various applications as organic materials.3 In this work, we have presented a highly robust one-pot, four-component cascade cyclization reaction of α-keto aldehydes, anilines, activated alkynes, and aromatic nucleophiles to synthesize a diverse range of pharmaceutically important penta-substituted pyrroles. The reaction proceeded smoothly under ball-milling conditions in presence of iron catalyst.
