摘要:
Several methods for the synthesis of cascade polymers (dendritic macromolecules) on adamantane have been investigated. The synthesis of two novel, branched monomers, 4-amino-4-(3-acetoxypropyl)-1,7-diacetoxyheptane and di-tert-butyl 4-amino-4-[2-(tert-butoxycarbonyl)ethyl]heptanedioate, possessing 3-fold symmetry and branches emanating from a tetrahedral carbon branch point, is described. These monomers were reacted with a monofunctional adamantane core to evaluate the reaction efficiency, ease of purification of products, and spectral characteristics.
