  • Chemoenzymatic synthesis of 2-oxabicyclo[3.3.1]nonan-3-one enantiomers via microbial reduction by Absidia coerulea AM 93
    作者:Teresa Olejniczak
    DOI:10.1016/j.molcatb.2009.11.005
    日期:2010.4
    Microbial enantioselective reduction of (+/-)-diethyl 2-(3-oxocyclohexyl)malonate (1) has been described. A screening test oil twenty-four fungi strains was carried Out. Most of the microorganisms preferred bioreduction of (+)-isomer of delta-ketoester (1) to (+)-trans delta-hydroxy ester (2) with the anti-Prelog selectivity. Biotransformation conditions using Absidia coerulea AM 93 were optimized with respect to the growth medium, temperature and pH. An effect of 48 chemical additives oil the Course of biotransformation was checked. (-)-Diethyl 2-((S)-3-oxocyclohexyl)malonate ((-)-1) (ee=98%) and (+)-diethyl 2-((1R, 3R)-3-hydroxycyclohexyl)malonate ((+)-2) (ee=99%)were isolated and subjected to chemical lactonization, leading to (+)-(1R, 5S)-2-oxabicyclo[3.3.1]nonan-3-one ((+)-3) and (-)-(1S, 5R)-2-oxabicyclo[3.3.1]nonan-3-one ((-)-3). The absolute configuration of product (-)-1 was confirmed by comparison of its optical rotation with the literature data. The absolute configuration the carbon atom hearing hydroxyl group in product (+)-2 was determined using the Mosher's ester. (C) 2009 Elsevier B.V. All rights reserved.

    The milbemycin β1 analogue (38) has been prepared by a convergent route involving the Wittig condensation between phosphonium salt (28) and 5-hydroxy-5H-furan-2-one (11), followed by diene isomerization, transprotection, lactonization, and reduction; the structure of the ester intermediate (37) was established by X-ray crystallography.

    DOI:10.1021/jo971047e
    日期:1997.10.1
    Samarium(II) iodide in conjunction with a catalytic low-valent transition metal species has been employed to promote the conjugate addition reaction of primary and secondary alkyl halides onto alpha,beta-unsaturated esters and amides. The method has been determined to be quite general and hence has been extended to the cyclization reactions of alkyl halides onto alpha,beta-unsaturated lactones, lactams
