Enantioselective Molybdenum-Catalyzed Allylic Alkylation Using Chiral Bisoxazoline Ligands. -The bisoxazolines shown in entry C) and D) are found to be good ligands in the enantioselective Mo-catalyzed allylic alkylation. With the acetate (Va) a branched/linear ratio of ΒΏ20:1 and an e.e. of 98% can
## Abstract New phosphoramidites were applied as chiral ligands in the Cuβcatalyzed allylic alkylation with dialkylzinc reagents. A variety of substrates, reagents and chiral ligands were screened, resulting in improved catalytic methodology for allylic bromides in which enantioselectivities up to
