(R)‐ and (S)‐3,4,5‐(MeO)3‐MeOBIPHEP have been identified as the efficient chiral ligands for the palladium‐catalyzedhighlyenantioselective synthesis of 2,3‐allenoates from different types of easily available racemic propargylic carbonates with 90–98 % ee and decent yields. The potential of the products was demonstrated with high chirality transfer efficiency.
