Dynamic kinetic protonation of racemic allenylmetal species for the asymmetric synthesis of allenic esters

The selective protonation of one enantiomer in a racemic mixture of allenylmetal compounds is possible with Pd0/SmI2 and a chiral alcohol (see reaction scheme below). The products, enantiomerically pure allenic esters, are an importa

Regio- and enantioselective synthesis of allenic esters by samarium(II)-mediated reduction of propargylic compounds through dynamic kinetic protonation

Regioselective synthesis of allenic esters was attained by SmI2-mediated reduction of propargylic phosphates and ethers bearing alkoxycarbonyl groups at the acetylene terminus. Using suitable chiral proton source in this system, highly enantio-
