enantioselective allylic C–H alkylation
of 1,4-pentadienes with 5H-thiazol-4-ones has been
developed. Under the cooperative catalysis of a palladium complex
of chiral phosphoramidite ligand and an achiral Brønsted acid,
a broad range of substituted 5H-thiazol-4-ones bearing
sulfur-containing tertiary chiral centers were accessed from the allylic
C–H alkylation in high levels of yields and enantioselectivities.
Alkyl and aryl 1,4-pentadienes led to linear and branched allylation
products, respectively.
