  Homochiral cyclopentane-based C1-symmetric P,P ligands C5H8(PPh2)(PR2) from C2-symmetric C5H8(PCl2)2

  摘要：

  Treatment of 1,2-trans-C5H8(PCl2)(2) with 1,2-C2H4(NHPr-i)(2) gave the C-2-symmetric perhydro-1,6,2,5-diazaphosphocine C5H8{P(Cl)N(Pr-i)CH2}(2)-cyclo, which produced dissymmetric C5H8(PPh2){P[N(Pr-i)CH2](2)-cyclo} on further reaction with PhMgBr. Cleavage of the P-N bonds with gaseous HCl afforded C5H8(PPh2)(PCl2), which was converted to C5H8(PPh2){P(OPh)(2)}(2) by reaction with phenol. All chiral P,P derivatives were obtained as racemates as well as resolved (1R,2R)-and (1S,2S)-enantiomers. (C) 2003 Elsevier Ltd. All rights reserved.

• Enantioselective Catalysis; 130: Optically Active Expanded Ligands Based on the trans-1,2-Substituted Cyclopentane Skeleton

  日期：1999.10

  New expanded bisphosphane ligands with a chiral trans-1,2-substituted cyclopentane skeleton were prepared. Polyaldehydes were accessible by coupling optically active bisphosphane precursors with branched aryl bromides. Optically active expanded ligands were obtained by condensation of the aldehydes with chiral amines and amino alcohols. The optically active ligands were tested in several model reactions of enantioselective catalysis, including allylic alkylation, hydrogenation (adopted to the use of water), and hydrosilylation.

  新扩展的双膦配体具有手性反式-1,2-取代环戊烷结构被制备出来。通过将光学活性的双膦前体与支链芳基溴化物偶联，可以获得多醛。通过将醛与手性胺和氨基醇缩合，获得了光学活性扩展配体。光学活性配体在多个手性选择性催化的模型反应中进行了测试，包括烯丙基烷基化、氢化（适用于水的使用）和氢硅化。

  The invention relates to novel trans-1,2-bis(dihalo- phosphino)-cycloalkanes (I) wherein the alkane moiety contains from 3 to 12 carbon atoms, trans-1,2-bis[di(X)-phosphino]cycloalkanes (II) wherein the alkane moiety contains from 3 to 12 carbon atoms and X is either hydrocarbyl or alkoxy and the resolved enantiometers of (II). Compounds (I) are produced by reacting a C3 to C12 cyclic olefin with a trivalent phosporous compound of the formula PX3 wherein X is chlorine or bromine in the presence of elemental phophorous. Compounds (I) are converted to compounds (II) by reaction with an (X)-containing carbon nucleophile.
