Zheng, Long-Sheng; Yin, Congcong; Wang, Fangyuan; Chen, Gen-Qiang; Zhang, Xumu published the artcile< Enantioselective synthesis of cis-hexahydro-γ-carboline derivatives via Ir-catalyzed asymmetric hydrogenation>, Name: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is tetrahydropyridoindole carboxylate iridium ZhaoPhos catalyst diastereoselective enantioselective hydrogenation; hexahydropyridoindole carboxylate preparation.
A novel synthetic route was developed for the construction of a chiral cis-hexahydro-γ-carboline derivative through Ir/ZhaoPhos-catalyzed asym. hydrogenation of corresponding tetrahydro-γ-carboline with high yields (up to 99% yield), excellent diastereoselectivities (up to >99 : 1 dr) and enantioselectivities (up to 99% ee), and high substrate-to-catalyst ratios (up to 5000).
Chemical Communications (Cambridge, United Kingdom) published new progress about Anilines Role: RCT (Reactant), RACT (Reactant or Reagent). 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Name: (9Z,12Z)-Methyl octadeca-9,12-dienoate.
