Yao, Guangkai; Wang, Bing-Feng; Yang, Shuai; Zhang, Zhi-Xiang; Xu, Han-Hong; Tang, Ri-Yuan published the artcile< DMSO-mediated palladium-catalyzed cyclization of two isothiocyanates via C-H sulfurization: a new route to 2-aminobenzothiazoles>, SDS of cas: 19241-24-8, the main research area is aryl isothiocyanate DMSO palladium bromide heterocyclization sulfurization tandem reaction; arylaminobenzothiazole preparation.
DMSO was found to activate arylisothiocyanates for self-nucleophilic addition A subsequent intramol. C-H sulfurization catalyzed by PdBr2 enable accessed to a wide range of 2-aminobenzothiazole derivatives in moderate to good yields. This is the first example of a DMSO-mediated Pd-catalyzed synthesis of 2-aminobenzothiazoles through cyclization/C-H sulfurization of two isothiocyanates.
RSC Advances published new progress about Aromatic amines Role: SPN (Synthetic Preparation), PREP (Preparation). 19241-24-8 belongs to class esters-buliding-blocks, and the molecular formula is C11H13NS, SDS of cas: 19241-24-8.
