應用

2,5-Dibromobenzenesulfonyl chloride may be used to synthesize 1,1-dimethylethyl (2S,4R)-4-{[(2,5-dibromophenyl)sulfonyl]amino}-2-methyl-1-pyrrolidinecarboxylate and 1-benzyl-2-(2,5-dibromophenyl)indole.
It may also be employed for the preparation of the following compounds:
  • methyl (2E)-3-[2-octyl-3-(2-methoxy-2-oxoethyl)-1,1-dioxido-2,3-dihydro-1,2-benzisothiazol-6-yl]acrylate
  • methyl (2E)-3-[2-(4-methoxyphenyl)-3-(2-methoxy-2-oxoethyl)-1,1-dioxido-2,3-dihydro-1,2-benzisothiazol-6-yl]acrylate
  • ethyl (2E)-3-[3-(2-ethoxy-2-oxoethyl)-2-(2-methoxybenzyl)-1,1-dioxido-2,3-dihydro-1,2-benzisothiazol-6-yl]acrylate

The development of a new method for the synthesis of 1,1-dioxido-1,2-benzisothiazoline-3-acetic acid by a domino process is reported whereby a classical Heck reaction is coupled to an intramolecular aza-Michael reaction. Ultimately, this method has been expanded to a one-pot, sequential

The direct arylation of N-protected 3-haloindole derivatives with benzenesulfonyl chlorides as coupling partners using 5 mol% of bis(acetonitrile)dichloropalladium(ii) catalyst and lithium carbonate as a base in 1,4-dioxane was investigated. We demonstrated that both iodo and chloro substituents at the indolyl

Genetic, epidemiologic, and biochemical evidence suggests that predisposition to Alzheimer's disease (AD) may arise from altered cholesterol metabolism, although the molecular pathways that may link cholesterol to AD phenotypes are only partially understood. Here, we perform a phenotypic screen for
