  • Application of Chitosan/Poly(vinyl alcohol) Stabilized Copper Film Materials for the Borylation of α, β-Unsaturated Ketones, Morita-Baylis-Hillman Alcohols and Esters in Aqueous Phase

    A chitosan/poly(vinyl alcohol)-stabilized copper nanoparticle (CP@Cu NPs) was used as a heterogeneous catalyst for the borylation of α, β-unsaturated ketones, MBH alcohols, and MBH esters in mild conditions. This catalyst not only demonstrated remarkable efficiency in synthesizing organoboron compounds but also still maintained excellent reactivity and stability even after seven recycled uses of the
    壳聚糖/聚(乙烯醇)稳定的铜纳米颗粒(CP@Cu NPs)被用作非均相催化剂,在温和条件下用于α,β-不饱和酮、MBH 醇和MBH 酯的硼基化。该催化剂不仅在合成有机硼化合物方面表现出显着的效率,而且即使在催化剂的七次循环使用后仍然保持优异的反应活性和稳定性。该方法提供了一种通过有效构建碳硼键来合成有机硼化合物的温和有效的方法。
  • Synthesis of Monoprotected 2-Alkylidene-1,3-propanediols by an Unusual SN2' Mitsunobu Reaction
    作者:Andre B. Charette、Bernard Cote、Sylvie Monroc、Sylvie Prescott
    DOI:10.1021/jo00126a046
    日期:1995.10
    A simple and efficient route to monoprotected (E)- and (Z)-2-alkylidene-1,3-propanediols is described. The key step involves an unusual regio- and stereoselective S(N)2' Mitsunobu reaction of substituted 3-hydroxy-2-methylenealkanoates which are readily available from a Baylis-Hillman reaction between methyl acrylate and an aldehyde. These allylic alcohols, when treated with PPh(3), a carboxylic acid, and DEAD in THF at temperatures ranging from -40 degrees C to 22 degrees C, produced the corresponding 2-alkylidene-3-hydroxypropanoate derivatives (or (E)-2-(hydroxymethyl)-3-substituted-2-alkenoate derivatives) in >70% with S(N)2':S(N)2 ratio of 22:1 to >50:1. It was found that weak and bulky carboxylic acids and low temperatures favor S(N)2' addition. The reaction conditions were effective for alkyl substituted derivatives, but the addition of Et(3)N to the Mitsunobu conditions was necessary to improve the S(N)2':S(N)2 ratios for the vinyl 19 and phenyl 20 derivatives. The monoprotected (Z)- and (E)-2-alkylidene-1,3-propanediols can be efficiently synthesized by a three-step sequence involving either a transesterification, protection, and DIBAL-H reduction (>80% overall yield) or by the chemoselective reduction, protection, and ester cleavage (67% overall yield).
  • Asymmetric Formal Synthesis of (+)-Lactacystin

    DOI:10.1002/ejoc.201402700
    日期:2014.10
    A formal synthesis of (+)-lactacystin was achieved from commercially available isobutyraldehyde and ethyl acrylate. A Baylis–Hillman reaction, an intermolecular nucleophilic displacement under Mitsunobu conditions, a Sharpless asymmetric epoxidation, a palladium(0)-catalyzed syn-selective ring opening of an epoxide by treatment with an azide, a one-pot azide reductive lactamization, and a ruthenium-catayzed
    (+)-lactacystin 的正式合成是由市售的异丁醛和丙烯酸乙酯实现的。Baylis-Hillman 反应、Mitsunobu 条件下的分子间亲核置换、Sharpless 不对称环氧化、钯 (0) 催化的环氧化物通过叠氮化物处理的顺式选择性开环、一锅叠氮化物还原内酰胺化和钌催化氧化被用作关键步骤。
