Catalytic asymmetric intermolecular C-H insertion of 1,4-cyclohexadiene with α-alkyl-α-diazoesters using chiral dirhodium(II) carboxylates
The first example of dirhodium(II) complex-catalyzed asymmetric intermolecular C-H insertion with α-alkyl-α-diazoesters is described. The reaction of 1,4-cyclohexadiene with 2,4-dimethyl-3-pentyl α-alkyl-α-diazoacetates under catalysis by dirhodium(II) te
Iridium(III) catalyzed diastereo- and enantioselective C-H bond functionalization
(Chemical Equation Presented) Iridium(III)-salen complexes were found to efficiently catalyze the enantioselective C-H carbene insertion. The insertion reaction at the α-position of tetrahydrofuran or at the methylene of 1,4-cyclohexadiene proceeded with
