Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 118430-78-7, is researched, Molecular C8H9N3S, about N,N-Dialkyl-N’-Chlorosulfonyl Chloroformamidines in Heterocyclic Synthesis. Part XII.* Synthesis and Reactivity of the Pyrazolo[3,4-e][1,2,4]thiadiazine Ring System, the main research direction is pyrimidothiadiazine preparation; pyrazolothiadiazine preparation; dialkylchlorosulfonyl chloroformamidine aminopyrazole dinucleophilic substitution methylation alkylation.Related Products of 118430-78-7.
N,N-Dialkyl-N’-chlorosulfonyl chloroformamidines 1 reacted regioselectively with 1-substituted 5-aminopyrazoles 2 via a 1,3-CCN dinucleophilic substitution to afford pyrazolo[3,4-e][1,2,4]thiadiazines 3 e. g., I, as the sole isolated products. Compounds 3, representatives of a very rare ring system, were shown to possess three nucleophilic sites at N2, N4, and N6. Methylation occurred at all three sites. Alkylation with benzylic halides occurred preferentially at N2, but some also occurred at N4, and at C7a. Alkylation with Et bromoacetate occurred at both N4 and N6, but the latter derivatives underwent a pyrazole ring expansion to afford pyrimido[4,5-e][1,2,4]thiadiazine derivs, e. g., II. Compounds 3 were unreactive towards various acylating agents.
