  Synthesis of enantiopure pyrrolidine and piperidine derivatives via ring closing metathesis

  摘要：

  The additions of lithiated allylsulfone carbanion to chiral N-sulfinylimines were found to proceed with good to excellent selectivity. The resulting intermediates 4a-d after transformation to dienylamides 7a-d and 16a-d, were converted to functionalized enantiopure piperidines and pyrrolines, respectively, via ring closing metathesis (RCM).

  The asymmetric intermolecular Heck reaction has been limited to aryl and vinyl triflates. Herein, we extend the reaction to aryl and vinyl bromides. Various cyclic olefins coupled with high enantioselectivity. Only bisphosphine oxides on a spiro backbone formed highly stereoselective Pd catalysts. The use of alcoholic solvents and alkylammonium salts were essential to promote halide dissociation from

  A modular approach employing indene as common starting material, has enabled the straightforward preparation in three reaction steps of P-thioether ligands for the Pd-catalyzed asymmetric allylic substitution. The analysis of a starting library of P-thioether ligands based on rational design and theoretical calculations has led to the discovery of an optimized anthracenethiol derivative with excellent

  采用茚作为通用起始原料的模块化方法使得能够在三个反应步骤中直接制备用于Pd催化的不对称烯丙基取代的P-硫醚配体。对P-硫醚配体的起始文库的分析基于合理的设计和理论计算，导致发现了一种优化的蒽硫酚衍生物，该衍生物在选择的反应中具有出色的行为。该配体改进了迄今为止报道的大多数方法，具有广泛的底物和亲核试剂范围。使用大量的C，N和O亲核试剂（总共40种化合物），对于一系列线性和环状烯丙基底物均具有出色的对映选择性。为了清楚地确定对映选择性的起源，已经通过NMR进一步研究了负责催化活性的物质。通过闭环复分解或Pauson-Khand反应衍生化了所得产物，以进一步证明制备对映纯复杂结构的方法的合成多功能性。

  The ring-closing metathesis (RCM) of two types of unsaturated chiral allylamines III, easily available from enantiomerically enriched epoxy alcohols, has been studied. Fully protected allylamines IIIa [(1)R = CH(2)-(CH(2))(n)()-CH=CH(2); (2)R = Boc; (3)R = PMB] have been prepared from unsaturated epoxy alcohols, whereas bis-allylamines IIIb ((1)R = Ph, (2)R = allyl,(3)R = Boc or PMB) have been prepared
