  手性C 2对称的2，5-二取代的吡咯烷衍生物作为二乙基锌与芳基醛反应的催化手性配体

  摘要：

  已经成功地合成了两种具有β-氨基醇部分的手性C 2对称的2，5-二取代的吡咯烷衍生物，并且在二乙基锌与芳基醛的反应中研究了它们的手性诱导催化能力。当N-（2'，2'-二苯基）时，可以以很高的化学收率（85-95％）和很高的对映体过量（ee）（70-96％）来生产具有R-绝对构型的仲醇。-2'-羟乙基）-（2 R，5 R）-双（甲氧基甲基）吡咯烷用作手性配体。另一方面，当N-甲基-（2 R，5 R） -双（diarylhydroxymethyl）吡咯烷被用作催化剂的配体，相应的EE秒-醇降低至20-45％，并且对映体选择性的一个有趣的反转的加成反应中观察到米氯代，p -氯-和米氟-苯甲醛与在相同反应条件下的二乙基锌。同时，我们还合成了一些手性C 2对称N-（β在相同的反应条件下，还研究了在吡咯烷环的2，5-位上具有不同空间大小的大体积取代基的β-羟乙基）吡咯烷衍生物及其手性诱导能力。此外，我们制备了简单的手性C

  Symmetry-Assisted Synthesis of C₂-Symmetric trans-α,α‘-Bis(hydroxymethyl)pyrrolidine and -piperidine Derivatives via Double Sharpless Asymmetric Dihydroxylation of α,ω-Terminal Dienes

  摘要：

  A new strategy has been developed for the synthesis of C-2-symmetric trans-alpha,alpha'-bis(hydroxymethyl)pyrrolidine and piperidine derivatives 1-3 starting from symmetric alpha,omega-terminal dienes 4-6. The double-asymmetric dihydroxylation (AD) reaction of 4-6 gave C-2-symmetric tetrols, which were converted in a four-step sequence to C-2-symmetric azacycloalkanes 17, 9, and 22, respectively. These azacycloalkanes were transformed into 1-3 in high enantiomeric excess (82% --> 98%ee). The double AD reaction proved to cause enantiomeric enhancement, even though the asymmetric induction for the first AD reaction is moderate. In addition, it was observed that the chromatography on silica gel of several C-2-symmetric azacycloalkanes (17, 20, and 22) of varying ee's resulted in marked enantiomeric fractionation.

  日期：1999.6

  Two novel chiral rhodium complexes were successfully synthesized from the reaction of a new class of bidentate nitrogen ligands with RhCl3. 3H(2)O in ethanol under reflux. The crystal structure of 4a was unambiguously established by X-ray analysis. Their corresponding cationic metal complexes prepared in situ from the reaction of 4a or 4b with AgBF4 catalyze the enantioselective allylation of arylaldehydes with allylstannane in 5-50% ee, (C) 1999 Elsevier Science Ltd.

  Two kinds of chiral C2-symmetric 2,5-disubstituted pyrrolidine derivatives having a β-aminoalcohol moiety have been successfully synthesized and their catalytic abilities of chiral induction have been examined in the reactions of diethylzinc with aryl aldehydes. The production of sec-alcohols having R-absolute configuration could be achieved in very high chemical yield (85–95%) and very high enantiomeric
