  Water-Accelerated Tandem Claisen Rearrangement−Catalytic Asymmetric Carboalumination

  摘要：

  The addition of stoichiometric quantities of water accelerates both the trimethylaluminum mediated aromatic Claisen reaction and the chiral zirconocene-catalyzed asymmetric carboalumination of terminal alkenes, The two reactions occur in a tandem sequence resulting in the selective formation of two new C-C and one C-O bond after oxidative quench of the intermediate trialkylalane.

  A highly efficient (aS)-Ir/In-BiphPHOX-catalyzed asymmetric hydrogenation of substituted 2H-chromenes and substituted benzo[e][1,2]oxathiine 2,2-dioxides is described. A series of 2H-chromenes and benzo[e][1,2]oxathiine 2,2-dioxides were hydrogenated to give the target products in high yields (92–99%) with excellent enantioselectivities (up to 99.7% ee) using our catalytic system. This reaction provides
