The protocol involves two synthetic steps with an initial solvent-free and catalyst-free synthesis of propargylated dihydropyrimidinone precursors using Biginelli condensations. The subsequent cycloaddition reactions of pyrimidinone alkynes with small peptide like azides prepared from Ugi or alternate Mannich type multi-component reactions afforded the triazole decorated pyrimidinone peptide conjugates

A series of indole peptidomimetics with potential for the future emergence as efficient therapeutic agents for stage 2 Human African Trypanosomiasis (HAT) is described. The peptidomimetics are constructed based on a build-pair concept using green chemistry models like multicomponent coupling strategy and click chemistry. The photophysical properties of the molecules are promising and point to the added possibilities of these molecules for the development of optical imaging agents. (C) 2016 Elsevier Ltd.

An efficient synthesis of ester-triazole-amide amphiphiles of coumarin derivatives by triazole randomization based on click approach is described. Twenty-five small peptide azides were synthesized using Ugi or alternate Mannich-type multi-component reactions. The new azides were then used for the triazole randomization of alkyne functionalized coumarin ester under CuAAC conditions. Sixty-five new peptide bio-hybrids are obtained in near quantitative yield with high regio and stereoselectivity. (C) 2012 Elsevier Ltd. All rights reserved.
