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, Tetrahedron Letters called Imidazobenzothiazine and primidobenzothiazine derivatives synthesis via an aliphatic SN2 substitution/Cu(I) catalyzed Ullmann coupling cascade process, Author is Wang, Ruihong; Qian, Weixing; Bao, Weiliang, which mentions a compound: 27231-36-3, SMILESS is SC1=NC2=CC(C)=CC=C2N1, Molecular C8H8N2S, COA of Formula: C8H8N2S.
An efficient method for the preparation of various imidazobenzothiazine and primidobenzothiazine derivatives from readily available 2-mercaptoimidazoles (thiouracils) and bromobenzyl bromides via a copper(I)-catalyzed one-pot cascade process has been developed. The reaction involves a SN2 process and an intramol. C-N cross coupling cyclization.
Although many compounds look similar to this compound(27231-36-3)COA of Formula: C8H8N2S, numerous studies have shown that this compound(SMILES:SC1=NC2=CC(C)=CC=C2N1), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
