Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Helvetica Chimica Acta called [4+2] Cycloaddition of α,β-unsaturated hydrazones. 3. Isothiazolo[4,5-b]pyridin-3(2H)-one 1,1-dioxides (4-azasaccharin derivatives), Author is Waldner, Adrian, which mentions a compound: 119639-24-6, SMILESS is O=C(C=C1)N(C(C)(C)C)S1(=O)=O, Molecular C7H11NO3S, Recommanded Product: 119639-24-6.
The [4 + 2] cycloaddition of α,β-unsaturated hydrazones, Me2NN:CHCR:CHR1 (R = Me, Et, CHMe2, R1 = H; R = R1 = Me), (1-azabuta-1,3-dienes) with isothiazol-3(2H)-one 1,1-dioxide derivatives I (R2 = H, CMe3, Me3CCH2CMe2, 4-ClC6H4, PhCH2, 4-MeOC6H4CH2) affords, depending on the solvent used, picolinamides II or III, and 4-azasaccharin derivatives IV or V. The course of the reaction is mainly influenced by the substituent R2 of the dienophile I.
In some applications, this compound(119639-24-6)Recommanded Product: 119639-24-6 is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
