  Optically active propargylic and allylic alcohols with a difluoromethyl group at the terminal carbon

  摘要：

  Enantioselective esterification of oc-substituted propargylic alcohols was found to proceed very smoothly in the presence of a catalytic amount of lipase (Nobozym 435) to yield the corresponding (R)-alcohols and (S)-acetates with high enantiomeric excess. Further, the preparation of optically active propargylic and allylic alcohols with a difluoromethyl group at the terminal carbon is described. (C) 1997 Elsevier Science Ltd.

  光氧化还原和镍催化合成手性烯丙基氨基甲酸酯。

  摘要：

  开发了一种温和且通用的有机光氧化还原/ Ni介导的方案，用于直接制备各种对映体富集的烯丙基氨基甲酸酯。报道的方法代表了烯丙基氨基甲酸酯经典一步一步合成的重大偏离。这种基于光氧化还原/镍的双重策略提供了无与伦比的能力，能够以较高的化学选择性和效率将衍生自1-溴代烯烃3-醇的烷基卤化物和手性氨基甲酸酯聚合统一。报道的光氧化还原/镍催化的交叉偶联反应不仅限于氨基甲酸酯，还包括其他O。衍生物，例如酯，醚，缩醛，碳酸酯或甲硅烷基醚。为了证明所报道方案的实用性，将所得的氨基甲酸烯丙酯通过对映体特异性方式的σ重排反应转化为功能化的非外消旋烯丙胺。该方法允许通过简单控制烯丙基氨基甲酸酯的双键的几何形状来合成对映异构烯丙基胺。

• The synthesis of non-racemic β-alkyl-β-aryl-disubstituted allyl alcohols and their transformation into allylamines and amino acids bearing a quaternary stereocenter
  作者：Aleksandra Narczyk、Michał Pieczykolan、Sebastian Stecko

  DOI：10.1039/c8ob00731d

  日期：——

  synthesis of non-racemic β-alkyl-β-aryl allyl alcohols and their transformation into allylamines bearing a quaternary stereogenic center is reported. The allyl alcohols were prepared either by Cu-catalyzed enantioselective reduction of enones or by sequential alkylation/hydrostannylation/Stille coupling of non-racemic propargyl alcohols. The prepared β-alkyl-β-aryl allyl alcohols were converted (after carbamoylation)

• Studies on Pd(II)-Catalyzed Coupling−Cyclization of α- or β-Amino Allenes with Allylic Halides
  作者：Shengming Ma、Fei Yu、Wenzhong Gao

  DOI：10.1021/jo0342469

  日期：2003.7.1

  The palladium-catalyzed coupling-cyclization of alpha- or beta-amino allenes with allylic halides leading to 3-allylic 2,5-dihydropyrroles and 1,2,3,6-tetrahydropyridines, respectively, was studied. The starting materials are easily available. The skeletons of both two classes of products were established by the X-ray diffraction studies of 7i and 9b. Through the study of the reaction of 2b with 3-chloro-1-butene, 1-chloro-2-butene, and pi-allyl palladium species and the stereochemical outcome of the coupling cyclization of (S)-2m and (R)-2n, it is believed that the current transformation most likely proceeded via a Pd(II)-catalyzed pathway, although a Pd(0) pathway cannot be completely excluded.
