Direct Generation of Acyclic Polypropionate Stereopolyads via Double Diastereo- and Enantioselective Iridium Catalyzed Crotylation of 1,3-Diols: Beyond Stepwise Carbonyl Addition in Polyketide Construction
Under the conditions of transfer hydrogenation employing a cyclometallated iridium catalyst (R)-I derived from [Ir(cod)Cl](2), allyl acetate, 4-cyano-3-nitrobenzoic acid and the chiral phosphine ligand (R)-SEGPHOS, α-methyl allyl acetate engages 1,3-propanediol 1a and 2-methyl-1,3-propanediol 1b in...
