New tricks of well-known aminoazoles in isocyanide-based multicomponent reactions and antibacterial activity of the compounds synthesized

Beilstein Journal of Organic Chemistry, 2017
The well-known aminoazoles, 3-amino-5-methylisoxazole and 5-amino-N-aryl-1H-pyrazole-4-carboxamides, were studied as an amine component in Ugi and Groebke–Blackburn–Bienaymé multicomponent reactions.

The multicomponent approach to N-methyl peptides: total synthesis of antibacterial (–)-viridic acid and analogues

Beilstein Journal of Organic Chemistry, 2012
Two syntheses of natural viridic acid, an unusual triply N-methylated peptide with two anthranilate units, are presented. The first one is based on peptide-coupling strategies and affords the optically active natural product in 20% overall yield over six

Novel postmodifications of the Ugi reaction

, 2016
In this thesis several novel postmodifiactions of regular Ugi-4CR products have been examined. Their scope and limitations were tested both by permutating the required functionalities around the Ugi scaffold and by synthesizing compound libraries for successful permutations. The following reactions were examined: 1.

Creating CMLReact from UsefulChem Ugi Reactions

, 2008
Cameron, Jean-Claude and I were invited to Peter's place in Cambridge, where we are now hacking on CMLReact for the Ugi reactions Jean-Claude has been working on. I just finished a script that uses the CDK and Sam's interface to the InChI library to convert a list of four reactants and one Ugi product into CMLReact (doi:10.1021/ci0502698).
