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.Beaudegnies, Renaud; Ghosez, Leon researched the compound: 2-(tert-Butyl)isothiazol-3(2H)-one 1,1-dioxide( cas:119639-24-6 ).Formula: C7H11NO3S.They published the article 《Asymmetric Diels-Alder reactions with chiral 1-azadienes》 about this compound( cas:119639-24-6 ) in Tetrahedron: Asymmetry. Keywords: asym Diels Alder azadiene; piperidine enantiomerically pure. We’ll tell you more about this compound (cas:119639-24-6).
Chiral 1-azadienes I (R1, R2 = H, Me) derived from α,β-unsaturated aldehyde and Enders’ hydrazines cycloadd to cyclic dienophiles with high facial selectivities. The adducts can be readily converted into enantiomerically pure piperidine derivatives, e.g. II.
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)Formula: C7H11NO3S, illustrating the importance and wide applicability of this compound(119639-24-6).
