  • Stereoselective addition of Grignard reagents to sulfinimines derived from tartrate diol (threitol): Generation of chiral building blocks for the collective total synthesis of lentiginosine, conhydrine and methyldihydropalustramate
    作者:Kavirayani R. Prasad、Vipin Ashok Rangari
    DOI:10.1016/j.tet.2019.130496
    日期:2019.9
    tartaric acid diol was undertaken. It was observed that the chirality of the inherent tartrate moiety influences the diastereoselectivity of the resultant sulfinamides formed in the reaction. The formed products serve as excellent building blocks for the synthesis of natural products. This has been demonstrated in the collective total synthesis of lentiginosine, (+)-α-conhydrine and methyldihydropalustramate
    对将格氏试剂添加到源自酒石酸二醇的亚磺胺中进行了系统的研究。观察到,固有酒石酸部分的手性影响反应中形成的亚磺酰胺的非对映选择性。形成的产品是合成天然产品的极好基础。这已在龙胆草碱,(+)-α-水合柠檬酸和甲基二氢palustramate的集体全合成中得到了证明。

    The transformation of the ‘fork head ketone’ 3b into the corresponding bicyclic lactone 13 via the Beckmann followed by the Huisgen–White rearrangement is described. Application of the method to a homochiral 2-etyl-substituted bicyclic ketone (+)-3dα gave efficiently (–)-dihydropalustramic acid (–)-2a, a degradation product from the alkaloid palustrine 1, in good optical yield.
    描述了通过贝克曼将“叉头酮” 3b转变为相应的双环内酯13 ,然后进行了惠斯根-怀特重排。该方法在同手性2-乙基取代的双环酮(+)-3dα上的应用可有效地产生(-)-二氢palustramic酸(-)-2a,这是生物碱palustrine 1的降解产物,具有良好的光学收率。
  • Studies toward the Synthesis of (+)-Palustrine:  The First Asymmetric Synthesis of (−)-Methyl Palustramate
    作者:Steven R. Angle、Robert M. Henry
    DOI:10.1021/jo980749g
    日期:1998.10.1
    (+)-palustrine, is described. The key step of the synthesis is a conformationally restricted Claisen rearrangement to afford the highly functionalized 1-benzylpipecolic ester 10. In addition, a new procedure for debenzylation of 1-benzylpiperidines (Li, (NH(2)CH(2))(2), Et(3)N, THF) was used to remove the benzyl protecting group where traditional methods failed.
    描述了(-)-甲基戊酸酯的立体选择性合成,这是合成(+)-芦丁碱的可能中间体。合成的关键步骤是构象受限的克莱森重排,以提供高度官能化的1-苄基哌酸酯10。此外,1-苄基哌啶(Li,(NH(2)CH(2))(2 ),Et(3)N,THF)用于除去传统方法失败的苄基保护基。
