Chen, Xue-Ping published the artcileOrganocatalytic Asymmetric Synthesis of Benzothiazolopyrimidines via [4 + 2] Cyclization of 2-Benzothiazolimines and Aldehydes, Category: thiazole, the publication is Journal of Organic Chemistry (2021), 86(2), 1667-1675, database is CAplus and MEDLINE.
The direct asym. synthesis of pyrimido[2,1-b]benzothiazoles using a com. available chiral amine catalyst was reported. A variety of 2-benzothiazolimines and aldehydes were well tolerated under the reaction conditions and generated the corresponding products in 81-99% yields with excellent diastereoselectivities and enantioselectivities (up to >20:1 dr, 99% ee). Furthermore, the products could be easily converted to other useful chiral building blocks.
Journal of Organic Chemistry published new progress about 95-24-9. 95-24-9 belongs to thiazole, auxiliary class Organic Pigment, name is 6-Chlorobenzothiazol-2-ylamine, and the molecular formula is C7H5ClN2S, Category: thiazole.
