Niu, Zhiqiang; He, Xinwei; Shang, Yongjia published the artcile< The efficient enantioselective synthesis of dihydropyrans via organocatalytic Michael addition reactions>, Product Details of C9H7BrO, the main research area is dihydropyran enantioselective preparation; cyanoketone alkenal enantioselective Michael addition organocatalyst.
An asym. Michael addition of α-cyanoketones to α,β-unsaturated aldehydes to form chiral dihydropyrans catalyzed by L-diphenylprolinol trimethylsilyl ether is presented. A series of 3,4-dihydropyrans were obtained in excellent yields (up to 91%) and enantioselectivities (up to 98% ee). A plausible mechanism for this process is proposed.
Tetrahedron: Asymmetry published new progress about Alkenals Role: RCT (Reactant), RACT (Reactant or Reagent). 3893-18-3 belongs to class bromides-buliding-blocks, and the molecular formula is C9H7BrO, Product Details of C9H7BrO.
