Bifunktionelle Isocyanide als Reagenzien zur Einführung von Isocyangruppen in Polystyrol‐Divinylbenzol‐Copolymere

Abstract

Bifunctional Isocyanides as Reagents for the Introduction of Isocyano Groups into Polystyrene‐Divinylbenzene Copolymers The synthesis of modified polystyrene‐divinylbenzene copolymers which are functionalized by isocyano groups (4, 6, 8) is described.

Multiple Multicomponent Macrocyclizations (MiBs): A Strategic Development Toward Macrocycle Diversity

“…It should be noted that Ugi already used such building blocks in an approach toward the synthesis of polymers. 62 In order to apply the same methodology to the synthesis of macrocycles, ways to favor the macrocyclization versus further oligomerization are required during the design of the building blocks and synthetic setup. As usual, dilution conditions, structural preorganization, or template effects are helpful to overcome the entropically disfavored ring closure from large acyclic precursors.…”
