In 2022,Blancou, Wafa; Jismy, Badr; Touil, Soufiane; Allouchi, Hassan; Abarbri, Mohamed published an article in Molecules. The title of the article was 《Simple and Expedient Access to Novel Fluorinated Thiazolo- and Oxazolo[3,2-a]pyrimidin-7-one Derivatives and Their Functionalization via Palladium-Catalyzed Reactions》.COA of Formula: C3H3BrN2S The author mentioned the following in the article:
An efficient, versatile, and one-pot method for the preparation of novel fluorinated thiazolo- and oxazolo[3,2-a]pyrimidin-7-ones is described from 2-aminothiazoles or 2-amino-oxazoles and fluorinated alkynoates. This transformation, performed under transition-metal-free conditions, offers new fluorinated cyclized products with good to excellent yields. Moreover, the functionalization of these N-fused scaffolds via the Suzuki-Miyaura and Sonogashira cross-coupling reactions led to the synthesis of highly diverse thiazolo- and oxazolo[3,2-a]pyrimidin-7-ones. In addition to this study using 5-Bromothiazol-2-amine, there are many other studies that have used 5-Bromothiazol-2-amine(cas: 3034-22-8COA of Formula: C3H3BrN2S) was used in this study.
5-Bromothiazol-2-amine(cas: 3034-22-8) belongs to anime. In organic chemistry, amines are compounds and functional groups that contain a basic nitrogen atom with a lone pair. Amines are formally derivatives of ammonia (NH3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group (these may respectively be called alkylamines and arylamines; amines in which both types of substituent are attached to one nitrogen atom may be called alkylarylamines).COA of Formula: C3H3BrN2S
