Quality Control of 2-(tert-Butyl)isothiazol-3(2H)-one 1,1-dioxide. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 2-(tert-Butyl)isothiazol-3(2H)-one 1,1-dioxide, is researched, Molecular C7H11NO3S, CAS is 119639-24-6, about A facile construction of 4-hydroxymethylbenzisothiazolone-1,1-dioxide.
4-Hydroxymethylbenzisothiazolone-1,1-dioxide could be facilely synthesized via a highly regioselective Diels-Alder cycloaddition between furfuryl alc. and 2-(tert-butyl)-isothiazolone-1,1-dioxide, followed by aromatization of the adduct under basic conditions. A secondary effect from intramol. hydrogen bonding influences the regioselectivity of the cycloaddition Unequivocal proof of the regiochem. of the Diels-Alder reaction is provided by X-ray crystallog. and ab initio calculations showed electronic and steric effects on transition structure asynchronicity.
In addition to the literature in the link below, there is a lot of literature about this compound(2-(tert-Butyl)isothiazol-3(2H)-one 1,1-dioxide)Quality Control of 2-(tert-Butyl)isothiazol-3(2H)-one 1,1-dioxide, illustrating the importance and wide applicability of this compound(119639-24-6).
