  Highly diastereoselective generation of various 3,3-disubstituted allyl boronates for the stereospecific construction of quaternary centers

  摘要：

  Single isomer trisubstituted olefins were converted into allyl boron nucleophiles that were condensed with aldehydes to give products containing quaternary centers. The products were obtained in extremely high diastereomeric ratios, a reflection of the stereochemical integrity of the starting materials. Crown Copyright (C) 2014 Published by Elsevier Ltd.

• Catalytic hydrogenation of α,β-unsaturated carboxylic acid derivatives using copper(<scp>i</scp>)/N-heterocyclic carbene complexes
  作者：Birte M. Zimmermann、Sarah C. K. Kobosil、Johannes F. Teichert

  DOI：10.1039/c8cc09853k

  日期：——

  air-stable copper(I)/N-heterocyclic carbene complex enables the catalytic hydrogenation of enoates and enamides, hitherto unreactive substrates employing homogeneous copper catalysis and H2 as a terminal reducing agent. This atom economic transformation replaces commonly employed hydrosilanes and can also be carried out in an asymmetric fashion.

• The Catalytic Addition of Alkyl Boranes to Alkynyl Esters Affording Single-Isomer Trisubstituted Olefins
  作者：William Ogilvie、Thivisha Rajagopal

  DOI：10.1055/s-0030-1259933

  日期：2011.5

  The generation of a series of trisubstituted olefins bearing alkyl substituents is described using a stereoselective and regio­selective addition to alkynyl esters. The method produces trisubstituted olefins as single isomers using a convenient and mild transformation in which alkyl boranes are cross-coupled with alkynyl esters and amides using palladium catalysis.
