Palladium-catalyzed allylic alkylation using pyridino-oxazolines and quinolino-oxazolines as ligands—influence of steric factors
摘要:
Four new chiral pyridino- and quinolino-oxazolines were subjected to the palladium-catalyzed alkylation of 1,3-diphenyl-2-propenyl acetate. The enantioselectivity varied (82-88% ee) with the steric properties of the ligands. The results are discussed in connection with results previously obtained using analogous ligands.
