  • Asymmetric Synthesis of (+)-Galbelgin, (−)-Kadangustin J, (−)-Cyclogalgravin and (−)-Pycnanthulignenes A and B, Three Structurally Distinct Lignan Classes, Using a Common Chiral Precursor
    作者:Claire E. Rye、David Barker
    DOI:10.1021/jo200968f
    日期:2011.8.19
    The enantioselective synthesis of three structurally distinct classes of lignan from a single, aza-Claisen-derived, chiral morpholine amide is reported. The class of lignan formed is dependent on the substitution pattern in the aryl rings and choice of protecting group on a key benzylic hydroxyl group. The methodology has been used to asymmetrically synthesize and determine the absolute stereochemistry
    据报道,从单一的,氮杂-克莱森衍生的手性吗啉酰胺中,对映体选择性合成了三种结构不同的木脂素。形成的木脂素的种类取决于芳基环中的取代方式和关键苄基羟基上保护基的选择。该方法已用于不对称合成和确定木脂素(+)-环没食子碱3,(-)-吡喃蒽烯A 4,(-)-吡喃蒽烯B 5和(-)-kadangustin J 8的绝对立体化学。
  • Bioinspired total synthesis of tetrahydrofuran lignans by tandem nucleophilic addition/redox isomerization/oxidative coupling and cycloetherification reactions as key steps

    DOI:10.1039/c7ob02848b
    日期:——
    A very short three-step approach to trans,trans,trans-2,5-diaryl-3,4-dimethyltetrahydrofuran lignans is reported. The carbon skeleton is assembled in a single step based on an unprecedented tandem reaction consisting of 1,2-addition of aryllithium reagents to α,β-unsaturated aldehydes, ruthenium-catalyzed redox isomerization of the resulting alkoxides to enolates and their dimerization triggered by
    据报道,反式,反式,反式-2,5-二芳基-3,4-二甲基四氢呋喃木脂素的非常短的三步法。碳骨架是基于空前的串联反应由一个步骤组装而成的,该串联反应由芳基锂试剂与α,β-不饱和醛的1,2-加成反应,钌催化的所得醇盐氧化还原异构化为烯醇化物以及它们的二聚反应引发。电子氧化。形成的2,3-二烷基-1,4-二酮具有中等至良好的d / l-非对映选择性,并通过还原和非对映选择性环醚化转化为目标四氢呋喃木脂素。

    作者:Sunit Hazra、Saumen Hajra
    DOI:10.1039/c3ra44573a
    日期:——
    An efficient and protection free asymmetric synthesis has been reported for all-trans variant 2,5-diaryl-3,4-disubstituted tetrahydrofuran lignans in seven steps from N-succinyl-2-oxazolidinone. (+)-Galbelgin and (+)-galbacin were synthesized in very good overall yields by this route where diastereoselective aldol reaction, stereoselective C-alkylation over O-alkylation and Friedel–Crafts reaction
