Abstract
Reaction of 5-(t-butyldiphenylsiloxy)propyloxyisophthalic with dodecan ol and diphenylphosphoryl azide (DPPA) affords the diurethane via Curt ius reaction. Removal of the silyl group affords an alcohol which unde rgoes similar reaction with,the isophthalic acid. Iteration of the pro cess affords dendritic wedges through generation four, which can be at tached to 1,3,5-benzenetricarboxylic acid in the same fashion. Materia ls are characterized by NMR and MALDI-TOF mass spectrometry. (C) 1998 Elsevier Science Ltd. All rights reserved.
