A Sunlight‐Induced Click Reaction as an Efficient Route to Cyclic Aliphatic Polyesters

17.04.2015 | Thomas Josse, Julien De Winter, Ozcan Altintas, Philippe Dubois, Christopher Barner‐Kowollik, Pascal Gerbaux, Olivie ..., Macromolecular Chemistry and Physics, 2015

To date, the controlled preparation of cyclic polymers is mainly achieved using click ligation strategies. The light‐induced Diels–Alder click coupling has recently been shown to function as an attractive catalyst‐free alternative to the copper‐catalyzed alkyne–azide cycloaddition. However, the ...

A Sequential Ugi Multicomponent/Cu-Catalyzed Azide–Alkyne Cycloaddition Approach for the Continuous Flow Generation of Cyclic Peptoids

13.04.2015 | Carlos Eduardo M. Salvador; Bartholomäus Pieber; Philipp M. Neu; Ana Torvisco; Carlos Kleber Z. Andrade; C. Oliver Kappe, The Journal of Organic Chemistry, 2015

The development of a continuous flow multistep strategy for the synthesis of linear peptoids and their subsequent macrocyclization via Click chemistry is described. The central transformation of this process is an Ugi four-component reaction generating the peptidomimetic core structure. In order ...
