  • Selective 1,4-Chiral Induction in the Reaction of Enolates Generated from<i>t</i>-Butyl δ-Hydroxy Carboxylates
    作者:Koichi Narasaka、Yutaka Ukaji、Kazutoshi Watanabe
    DOI:10.1246/bcsj.60.1457
    日期:1987.4
    Lithium enolates generated from t-butyl esters of δ-hydroxy carboxylic acids with lithium dialkylamides in THF–HMPA were alkylated stereoselectively to give the corresponding syn-α-alkylated δ-hydroxy esters. The generation of the enolates was accelerated by the addition of lithium trifluoromethanesulfonate, and the successive aldol and hydroxylation reactions of the enolates also proceeded in a stereoselective manner.
    在THF-HMPA体系中,由δ-羟基羧酸的叔丁酯和二烷基锂酰胺生成锂烯醇盐,随后立体选择性地进行烷基化反应,得到相应的顺式-α-烷基化δ-羟基酯。通过添加三氟甲磺酸锂可加速烯醇盐的生成,并且烯醇盐的连续aldol反应和羟基化反应也以立体选择性方式进行。
  • Remote Control of Regio- and Diastereoselectivity in the Hydroformylation of Bishomoallylic Alcohols with Catalytic Amounts of a Reversibly Bound Directing Group
    作者:Christian U. Grünanger、Bernhard Breit
    DOI:10.1002/anie.200905949
    日期:2010.1.25
    Remote and reversible! Phosphinites serve as reversibly bound directing groups for the remote control of the regio‐ and diastereoselective hydroformylation of bishomoallylic alcohols (see scheme; r.r: regioisomer ratio). The distance between the double bond and the functional hydroxy group to which the directing group is reversibly bound is the longest ever reported.
    远程且可逆!次膦酸酯是可逆结合的导向基团,用于远程控制双烯丙基烯丙醇的区域和非对映选择性加氢甲酰化(请参阅方案; rr:区域异构体比率)。双键与可逆结合的方向性羟基基团之间的距离是有史以来最长的。
  • Palladium-catalysed conversion of alkenols into five- and six-membered ring lactones at room temperature and atmospheric pressure
    作者:Howard Alper、Danielle Leonard
    DOI:10.1039/c39850000511
    日期:——
    Unsaturated alcohols react with carbon monoxide, oxygen, palladium chloride, copper(II) chloride, and hydrochloric acid in tetrahydrofuran to give lactones in 42–80% yield.
    不饱和醇与一氧化碳,氧气,氯化钯,氯化铜(II)和盐酸在四氢呋喃中反应,以42-80%的收率得到内酯。
  • Natural product synthesis using π-allyltricarbonyliron lactone complexes: Synthesis of parasorbic acid, the carpenter bee pheromone and malyngolide
    作者:Averil M. Horton、Steven V. Ley
    DOI:10.1016/0022-328x(85)87394-0
    日期:1985.4
    Preparation of three δ-lactonic natural products, parasorbic acid, the carpenter bee pheromone and malyngolide has been achieved from π-allyltricarbonyliron lactone complexes as the key synthetic intermediates.

  • Stereocontrolled synthesis of (R*R*)- and (R*S*)-5-hydroxy-2-methylhexanoic acid lactones
    作者:J.E. Bäckvall、S.E. Byström、Nyström J.E.
    DOI:10.1016/s0040-4020(01)91414-0
    日期:1985.1
    (E,Z)-2,4-Hexadiene was transformed to the lactone cis-1 ( ⪢ 93% cis)(pheromone of the carpenter bee) in a stereospedfic reaction sequence via a Pd-calalyzed 1,4-acetoxychlorination. The same reaction sequence applied to (E,E)-2,4-hexadiene afforded the isomeric lactone trans-1 (⪢91% trans).
    (E,Z)-2,4-己二烯转化成内酯顺- 1(⪢93%顺式在stereospedfic反应序列)(木匠蜂的信息素)经由一个钯calalyzed 1,4- acetoxychlorination。相同的反应顺序施加到(E,E)-2,4-己二烯,得到同分异构的内酯反式- 1(⪢91%反式)。
