  • Enantioselective α-alkylation of unsaturated carboxylic acids using a chiral lithium amide
    作者:Eva M. Brun、Salvador Gil、Margarita Parra
    DOI:10.1016/s0957-4166(01)00152-5
    日期:2001.4
    The regio- and stereochemistry of the alkylation of dienediolates from unsaturated carboxylic acids with benzylic halides, which often results in mixtures of isomers, can be controlled by means of changes in the lithium amide, allowing the α-regioisomer to be obtained as the major diastereoisomer. In addition, when chiral amines are used, moderate enantiomeric excesses can be attained.
    来自不饱和羧酸与苄基卤化物的二烯二醇酯烷基化的区域和立体化学(通常会导致异构体的混合物)可以通过改变氨基锂来控制,从而可以将α-区域异构体作为主要的非对映异构体获得。另外,当使用手性胺时,可以获得中等的对映体过量。
  • Lithium enediolates and dienediolates of carboxylic acids in synthesis: Alkylation with secondary halides
    作者:Eva M. Brun、Salvador Gil、Ramón Mestres、Margarita Parra
    DOI:10.1016/s0040-4020(98)00957-0
    日期:1998.12
    High yields in the alkylation of dianions of alpha,beta-unsaturated carboxylic acids with secondary halides can be obtained despite elimination reactions occurring. alpha-Regioselectivity for the alkylation of but-2-enoic acids (1-4) is seldom obtained. Although double bond stereoselectivity is higher than 99% for gamma-alkylated products, stereoselectivity is rather poor for most of the alpha-alkylated products. (C) 1998 Elsevier Science Ltd.

  • Regiocontrol in Alkylation of Lithium Dienediolates of Unsaturated Carboxylic Acids
    作者:Eva M. Brun、Salvador Gil、Margarita Parra
    DOI:10.1055/s-2001-9721
    日期:——
    Alkylation of dienediolates from unsaturated carboxylic acids with benzylic halides often results in mixtures of regioisomers. However it can be controlled by adequate modification of the reaction conditions. Thus, addition of DMI leads mainly to the α-regioisomer, whereas addition of 12-crown-4 allows to obtain the γ-regioisomer as the major product from the same reactants.
    用苄基卤化物对来自不饱和羧酸的二烯二醇盐进行烷基化,通常会导致区域异构体混合物的产生。然而,这可以通过对反应条件的适当改良来控制。因此,加入DMI主要导致α-区域异构体的生成,而加入12-冠-4则允许从相同反应物中获得作为主要产物的γ-区域异构体。
