  Facile synthesis of proline based phosphineoxazoline ligands by formation of a PN bond

  摘要：

  A series of new P-N ligands in which the phosphorus moiety is introduced by Formation of a phosphorus-heteroatom bond are synthesized. These ligands are based on proline with chiral centers from both proline and an oxazoline. The two chiral centers are responsible for the observed stereoselectivity. Palladium complexes of these ligands are shown to be effective in the allylation of dimethyl malonate as well as amination of allyl acetates. (C) 2002 Elsevier Science Ltd. All rights reserved.

  phosphine–oxazoline ligands is reported. This ligands are synthesized by reaction of a phosphine chloride with the secondary nitrogen of proline. Upon coordination to iridium the resulting complexes can be used in the asymmetric hydrogenation of simple olefins. The effect of different counter ions and substitution at the oxazoline and the phosphine is reported.
