Enantioselective synthesis of the ester side chain of homoharringtonine

Details of the synthesis of the methyl ester of the side chain of homoharringtonine, a natural product with antileukemic properties, are reported below. The key tactical element involved a Michael addition between the known chiral imine 4 and 2-acetoxyacr

Enantioselective synthesis of the ester side chain of homoharringtonine

The Michael adduct 6 was converted in ten steps with an overall yield of 5.7% into the methyl ester derivative of the side chain of homoharringtonine, (R)-17.
