The present application relates to novel 7-sulfanylmethyl-, 7-sulfinylmethyl- and 7-sulfonylmethylindole derivatives, processes for the preparation thereof, the use thereof alone or in combinations for the treatment and/or prevention of diseases, and the use thereof for the manufacture of medicaments for the treatment and/or prevention of diseases, especially for the treatment and/or prevention of cardiovascular disorders.
commercially available aldehydes (ketones) and benzylic alcohols can be readily arylated to provide a general and scalable access to structurally diverse alcohols (97 examples, >10 gram‐scale). More importantly, convergentpairedelectrolysis, the ideal but challenging electrochemical technology, was employed to transform low‐value alcohols into more useful alcohols. Detailed mechanism study suggests that two

Arylboronic acids react with aldehydes and α,β-unsaturatedcarbonylcompounds in the presence of a base and a catalytic amount of a palladium(0) complex with chloroform, affording the corresponding addition products in good yields, and chiral benzhydrol was obtained with up to 43% e.e. using (S,S)-bppm as a ligand. General palladium complexes have no catalytic activity without chloroform. Because chloroform

cross-coupling strategy that enables the direct arylation of carbonyl/iminyl derivatives in the presence of Et3N has been realized. Such an atom-economical protocol furnishes a broad scope of arylation products such as secondary/tertiary alcohols and amines via a PCET process that facilitates the challenging reduction of C═X (X = O, N). Mechanisticinvestigation indicates two photocatalytic redox cycles
Extended scope of in situ iodotrimethylsilane mediated selective reduction of benzylic alcohols

日期:——
Iodotrimethylsilane, generated in situ from chlorotrimethylsilane and sodium iodide in acetonitrile, selectively reduces moderately electron deficient benzylic alcohols to the analogous toluenes; other reduction sensitive functional groups such as ketone, aldehyde, nitrile, and nitro are unaffected.
