First Enantioselective Total Synthesis of the Reported Structure of (R)-(+)-Orizaterpenyl Benzoate Using an Asymmetric Allylation of a Prochiral Ketone in a Domino Process

Abstract

An efficient synthesis of (R)-orizaterpenyl benzoate using a multicomponent domino allylation reaction of a prochiral ketone with allyltrimethyl silane and the enantiopure silyl ether of benzyl phenyl carbinol in the presence of catalytic amounts of TfOH is described.
