Bis(1,3-dihydroxy-isopropyl)amine (BDI) as an AB4 dendritic building block: rapid synthesis of a second generation dendrimer
摘要:
Bis(1,3-dihydroxy-isopropyl)amine (BDI) 1, a symmetrical AB(4) dendritic building block, is developed into two diamine linkers in which the nitrogen is more nucleophilic. The four primary alcohols in BDI undergo Michael reactions with t-butyl acrylate. Branch cells of this rare multiplicity allow the rapid construction of a second generation dendrimer 5 with 48 protected peripheral primary alcohol groups. (C) 2000 Elsevier Science Ltd.

Derivatives of bis-(1,3-dihydroxy-prop-2-yl)amine are disclosed, together with the use of such derivatives and of bis(1,3-dihydroxy-prop-2-yl)amine itself in the preparation of polymers, in particular dendrimers. Some of the derivatives may be useful as non-ionic surfactants.
