    摘要:
    cis-4-Hydroxy-5-(iodomethyl)-4,5-dihydro-2(3H)-furanones (1 and ent-1) were converted by cross-coupling with several Grignard-derived cuprates followed by benzoylation and base-induced elimination into new chiral butenolides 12, 14, ent-14, 20, and 27. The sequential conjugate addition-quenching of these butenolides under complete stereocontrol provided several polysubstituted gamma-butyrolactones including flavor components [(+)-trans-whisky lactone (3) and (+)-trans-cognac lactone (4)], the antitumor antibiotic lactone (-)-methylenolactocin (5), and lichen components [(+)-nephrosteranic acid (7) and (+)-roccellaric acid (8)].

    日期:2010.2.12
    A simple and efficient approach to (+)-nephrosteranic acid from dodecanol as a starting material is described, employing Sharpless asymmetric epoxidation, ring-closing metathesis, and Gilman addition of a vinyl group as key steps. These key reactions allow fast access to trisubstituted γ-butyrolactone. The molecule synthesized exhibits potent antifungal, antibacterial, and cytotoxic activities against
    描述了一种以十二烷醇为原料制备 (+)-肾甾烷酸的简单而有效的方法,采用 Sharpless 不对称环氧化、闭环复分解和吉尔曼加成乙烯基作为关键步骤。这些关键反应可以快速获得三取代的 γ-丁内酯。合成的分子对所有测试菌株均表现出有效的抗真菌、抗菌和细胞毒性活性。

    (+)- and (-)-Nephrosteranic acid (16) have been prepared in an enantioselective fashion from alkyne acid 19 (or ent-19) by a three step sequence involving debenzylation-lactonization, oxidative cleavage, and selective epimerization at C-4. Acids 19 and ent-19 were obtained as single enantiomers employing a Nicholas-Schreiber reaction.

    日期:2019.6.7
    N-heterocyclic carbene (NHC) catalysis of maleimides with alkyl aldehydes is established for the synthesis of 3-acylsuccinimides. The first dynamic kinetic resolution of 3-acylsuccinimides is accomplished through asymmetric transfer hydrogenation. These two catalytic methodologies are utilized for the synthesis of each enantiomer of trans-paraconic acids in three steps and cis-paraconic acids in four steps

    3-dioxolandimethanol) cyclohexadienyl Ti derivative with various aldehydes led to the corresponding homoallylic alcohols with excellent diastereo- and enantioselectivities. Lower selectivities were obtained with chiral B-cyclohexadienyldiisopinocampheylborane. The 1,3-cyclohexadienes are very useful building blocks for the preparation of biologically important gamma-butyrolactones. Short efficient syntheses of (+)-nephrosteranic
    我们提出了环己二烯从3金属1,4-环己二烯到各种醛的立体选择性转移。路易斯酸介导的醛的“烯丙基化”通过3-甲硅烷基化和3-苯乙烯基化的1,4-环己二烯的处理不能以高非对映选择性实现。相反,环己二烯基钛化合物与脂族和芳族醛的反应均具有优异的非对映选择性。手性TADDOL衍生的(TADDOL,2,2-二甲基-α,α,α',α'-四苯基-1,3-二氧代兰二甲醇)环己二烯基Ti衍生物与各种醛的反应导致相应的均丁醇具有出色的非对映体和对映选择性。用手性B-环己二烯基二异硫代樟脑硼烷获得较低的选择性。1 3-环己二烯是制备生物学上重要的γ-丁内酯的非常有用的结构单元。描述了通过1,4-环己二烯的不对称化来短效地合成(+)-肾甾酸,(+)-反式威士忌内酯和(+)-反白兰地内酯。
