摘要:
The coupling reaction between 2-p-totylsulfinyl benzaldehyde and substituted boronic acids catalyzed by Pd-2(dba)(3)center dot CHCL3 proceeds in a stereoselective manner, demonstrating the efficiency of the sulfinyl group as a chiral inductor. Enantiopure secondary diaryl alcohols become easily accessible by subsequent sulfoxide-lithium exchange. (C) 2007 Elsevier Ltd. All rights reserved.
