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.
