Synthesis of chiral 2,2′-dimethyl-1,1′-binaphthyl-8,8′-diamine and barriers of atropisomerization of the related binaphthyls
摘要:
Chiral 2,2'-dimethyl-1,1'-binaphthyl-8,8'-diamine 3b was synthesized via a diastereomeric resolution and determination of the absolute configurations, and the barriers compared for atropisomerization amongst binaphthyl skeletons. (c) 2007 Elsevier Ltd. All rights reserved.
