Zhang, Tian-Yuan; Deng, Yi; Wei, Kun; Yang, Yu-Rong published the artcile< Enantioselective Iridium-Catalyzed Allylic Alkylation of Racemic Branched Alkyl-Substituted Allylic Acetates with Malonates>, Safety of (R)-2,2′-Bis(diphenylphosphino)-5,5′,6,6′,7,7′,8,8′-octahydro-1,1′-binaphthyl, the main research area is alkenyl ester preparation enantioselective; alkyl substituted allylic acetate malonate allylic alkylation iridium catalyst.
The regio- and enantioselective allylic substitution of branched alkyl-substituted allylic acetates employing malonates was achieved through a process that called for Krische’s π-allyliridium C,O-benzoate catalyst. The protocol reported herein was applied to a diverse set of branched alkyl substrates that are generally not well tolerated in the other two types of Ir-catalyzed allylation.
