Amino Acid-Viologen Hybrids: Synthesis, Cucurbituril Host-Guest Chemistry, and Implementation on the Production of Peptides

J Org Chem. 2022 Jan 7;87(1):760-764. doi: 10.1021/acs.joc.1c02040. Epub 2021 Dec 10.

Abstract

We present herein the development of a series of viologen-amino acid hybrids, obtained in good yields either by successive alkylations of 4,4'-bipyridine, or by Zincke reactions followed by a second alkylation step. The potential of the obtained amino acids has been exemplified, either as typical guests of the curcubituril family of hosts (particularly CB[7]/[8]) or as suitable building blocks for the solution/solid-phase synthesis of two model tripeptides with the viologen core inserted within their sequences.
