Late‐Stage Functionalization of Peptides on the Solid Phase

Angewandte Chemie International Edition, EarlyView.
Peptide modifications are essential to control pharmacodynamic and pharmacokinetic properties of peptide drugs. Consequently, strategies that allow for efficient and rapid incorporation of non‐canonical modifications into peptides in parallel formats are highly sought after.

Multicomponent Syntheses of glycoside-decorated N-heterocyclic pharmacophores

, 2006
We report in this communication on the synthesis of carbohydrate decorated N-heterocycles, namely dihydropyrimidin-2-ones, dihydropyridines, and azetidin-2-ones, via multicomponent Biginelli, Hantzsch, and Staudinger reactions ...
