  Avoiding the classical resolution during the synthesis of MeO-BIPHEP and 3,3′-disubstituted derivatives

  摘要：

  The Ullmann coupling of 1 (R = H) gives a 2:1 mixture of diastereomers 2 (R = H) in 81% yield that are easily separated by silica gel chromatography. This procedure avoids the generally cumbersome and sometimes difficult resolution step with DBTA. Similar Ullmann couplings and separation of the corresponding diastereomers are employed with other derivatives of I (R = OtBu, iPr, Ph, and mesityl) ultimately affording a new series of 3,3'-disubsituted-MeO-BIPHEP derivatives. The use of these new derivatives in palladium-catalyzed asymmetric Heck reaction, Pd-catalyzed polyene cyclizations and rhodium-catalyzed hydrogenations is also reported. (c) 2005 Elsevier Ltd.

  auxiliary is described that provides only one diastereomer during intramolecular Ullmann couplings. Treatment of five Ullmann coupling precursors with Cu powder in DMF at 115 degrees C provides 2,2',3,3',6,6'-hexasubstituted 1,1'-biphenyls as single diastereomers in yields ranging from 66% to 91%.

  [反应：见正文]描述了一种手性助剂，在分子内Ullmann偶联过程中仅提供一种非对映异构体。在115摄氏度的DMF中用铜粉处理五种Ullmann偶联前体，得到2,2'，3,3'，6,6'-六取代的1,1'-联苯作为单一非对映异构体，收率范围为66％至91％ 。
