Upper rim appended hybrid calixarenes via click chemistry

Org Lett. 2007 Sep 13;9(19):3713-6. doi: 10.1021/ol071047t. Epub 2007 Aug 15.

Abstract

We report the application of "click" chemistry for the synthesis of hybrid calixarenes appended on the upper rim with carbohydrate and N,C-protected alpha-amino acids. The chemoselective N- or C-deprotection of the alpha-amino acids and their subsequent transformation into dipeptides is described. The first example of a chemo-enzymatic synthesis on upper rim derived calix[4]arenes using trans-sialidase affords sialylated lactose calix[4]arenes. Our innovative chemo-enzymatic process paves the way for further applications.
