[摘要]:The ability of a chiral isothiourea to promote the regio- and enantioselective O- to C-carboxyl transfer of a series of 3-alkyl-5-aryl- and 5-methyl-3-phenylfuranyl carbonates is examined, generating preferentially the alpha-regioisomers (alpha/gamma up to 83:17) with high asymmetric induction (up to 83% ee). |
