Pyrrolidinodiones in Enol-Ugi, Enol-Passerini, and Anomalous Enol-Passerini Condensations

open access: yesProceedings, 2019
In continuation of our recent research on the development of novel multicomponent reactions with isocyanides, we have used, for the first time, enols as the acid components in Ugi- and Passerini-type reactions. Thus, electron-poor pyrrolidinodiones react

Multicomponent Reactions of Isocyanides for the Preparation of Low Molecular Weight Gelators: Preliminary Studies

open access: yesChemistry Proceedings, 2021
Low molecular weight gelators, LMWGs, are small molecules that can self-associate in organic solvents or in water to form fibrous supramolecular architectures and three-dimensional networks that present important applications in several fields.

Site‐Specific Protein Bioconjugation Through Cellular Incorporation of Noncanonical Amino Acids

open access: yesAngewandte Chemie, EarlyView.
Genetic code expansion (GCE) enables site‐specific installation of noncanonical amino acids containing bioorthogonal conjugation handles, allowing precise, homogeneous protein modification. This review examines the principles of orthogonal translation, surveys the chemistries available for chemoselective labeling, and highlights emerging multi‐site ...

Macrocyclization of ω‐Isocyano Aldehydes

open access: yesAngewandte Chemie, EarlyView.
The ω‐isocyano aldehydes readily undergo cyclization to afford α‐acyloxy, α‐hydroxy, α‐acetamido, and α‐keto macrolactams, as well as tetrazole‐fused macrocycles, via C(sp3)─C(sp2) bond formation, providing access to diverse α‐functionalized medium‐sized lactams and macrolactams. ABSTRACT Medium‐sized rings and macrocycles constitute a privileged class
