Synthesis of complex allylic esters via C-H oxidation vs C-C bond formation.

ABSTRACT: A highly general, predictably selective C-H oxidation method for the direct, catalytic synthesis of complex allylic esters is introduced. This Pd(II)/sulfoxide-catalyzed method allows a wide range of complex aryl and alkyl carboxylic acids to couple directly with terminal olefins to furnish (E)-allylic esters in synthetically useful yields and selectivities (16 examples, E/Z >or= 10:1) and without the use of stoichiometric coupling reagents or unstable intermediates. Strategic advantages of constructing allylic esters via C-H oxidation vs C-C bond-forming methods are evaluated and discussed in four "case studies".
