  • Enantioselective, Catalytic One‐Pot Synthesis of <i>γ</i> ‐Butyrolactone‐Based Fragrances
    作者:Ceyda Kumru、Thomas Classen、Jörg Pietruszka
    DOI:10.1002/cctc.201801040
    日期:2018.11.7
    Herein the preparative (1 g scale), stereoselective syntheses of various alkyl‐substituted γ‐butyrolactone fragrances 1 is described. The α,β‐unsaturated γ‐keto esters 2 as starting materials were synthesized by a HornerWadsworthEmmons reaction and are further reduced by an ene reductase and alcohol dehydrogenase in a one‐pot enzyme cascade to nine desired γ‐butyrolactones 1, among them whisky (1 c)
    本文描述了各种烷基取代的γ-丁内酯香料1的制备(1 g规模)的立体选择性合成。以Horner-Wadsworth-Emmons反应合成作为原料的α,β-不饱和γ-酮酸酯2,并通过单罐酶级联反应中的烯还原酶和醇脱氢酶进一步将其还原为九种所需的γ-丁内酯1,其中威士忌(1 c)和白兰地内酯(1 d)。产品1以中等至良好的收率和非常好的非对映选择性获得了C。此外,对n Bu取代基的位置进行了置换,以研究其对酶级联反应的影响。
  • Dichotomous regiochemistry of aldehyde and ketone in the reaction with dithio-substituted crotyllithium

  • Enhancement of enantiocontrol/diastereocontrol in catalytic intramolecular cyclopropanation and carbon-hydrogen insertion reactions of diazoacetates with Rh2(4S-MPPIM)4
    作者:Michael P. Doyle、Qi-Lin Zhou、Alexey B. Dyatkin、Daniel A. Ruppar
    DOI:10.1016/0040-4039(95)01561-u
    日期:1995.10
    Dirhodium(II) tetrakis[methyl 1-(3-phenylpropanoyl)imidazolidin-2-one-4(S)-carboxylate], Rh-2(4S-MPPIM)(4), provides significant enhancement in enantiocontrol for intramolecular cyclopropanation reactions of allylic diazoacetates and optimal enantiocontrol/diastereocontrol for intramolecular C-H insertion reactions of secondary alkyl diazoacetates.
  • Regio- and diastereoselective reactions of dithio-substituted crotyllithium and aldehydes
    作者:Jim Min Fang、Li Fan Liao、Ber Cherng Hong
    DOI:10.1021/jo00364a045
    日期:1986.7
  • A stereochemical study on the intramolecular hydrosilylation of α,β-unsaturated esters
    作者:Scott E. Denmark、David C. Forbes
    DOI:10.1016/s0040-4039(00)61182-6
    日期:1992.8
    The intramokcular hydrosilylation of several 3-methyl-4-siloxy-2-butenoates afforded cis disubstituted lactones after desilylation. The diastereoinduction was sensitive to the bulk of the allylic substituent, but not to the groups on silicon. The origin of asymmetric induction is believed to be the A1,2 strain from the beta-methyl group.
