    名称:
    Improvement of the chemoenzymatic synthesis of both enantiomers of keto-protected 4-amino-2-pentanone
    摘要:
    An improved enantioselective synthesis (five steps, 37-44% yield versus seven to 10 steps, 13.5 and 12% yield, respectively) of both enantiomers of keto-protected 4-amino-2-pentanone has been realized, the key step being the microbiological reduction of 2,4-pentanedione. This study shows that microbiological reductions of the mono acetal-protected 2,4-pentanedione afforded in most cases the corresponding ketol with moderate to excellent enantiomeric excesses, depending on the microorganism used.

    an ester/amide exchange, and the use of the resulting β-hydroxy amide for the acylation of an organometallic compound. We shortened this route by showing that β-keto Weinreb amides are hydrogenated with up to 99 % ee in the presence of [Me2NH2]+[RuCl(S)-BINAP]2(µ-Cl)3}– (0.5 mol-%) at room temp./5 bar. These Weinreb amides were prepared by seemingly obvious yet unprecedented condensations of lithiated

    1,4-Disilylation of β,β-unsaturated ketones with 1,1-dichloro-l-phenyl-2,2,2-trimethyldisilane proceeded in the presence of phosphine-palladium catalysts in benzene. High enantio-selectivity (up to 92%) was observed in the disilylation with dichloro[(R)-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl]palladium(II) as a catalyst (0.5 mol %).
