Catalytic Enantioselective Functionalization of Maleimides: An Update

Chinese Journal of Chemistry, Volume 42, Issue 24, Page 3605-3622, 15 December 2024.
Maleimides are multisite‐reactive scaffolds that have stimulated a growing interest in the field of synthetic organic chemistry. The present review covers the utilization of maleimides as electrophilic partners and pro‐nucleophilic partners in metal‐catalyzed or organocatalyzed functionalizations with the control of either central and/or axial ...

1,2‐Diaza‐1,3‐Dienes as a Multifaceted Synthons for the Synthesis of Heterocycles: A Fifteen‐Years Update

European Journal of Organic Chemistry, Volume 27, Issue 44, November 25, 2024.
1,2‐Diaza‐1,3‐butadienes, also called azoalkenes, have received considerable attention as key synthons for constructing various heterocyclic scaffolds. This minireview summarizes the contribution of our group in this field over the period from 2009 to the present, focusing on the role of the azoene building block in forming the heterocyclic structures.

Thermal and Photoinduced Radical Cascade Annulation using Aryl Isonitriles: An Approach to Quinoline‐Derived Benzophosphole Oxides

Angewandte Chemie International Edition, Volume 63, Issue 30, July 22, 2024.
The synthesis of quinoline‐based benzophosphole oxides from ortho‐alkynylated aromatic phosphine oxides and aryl isonitriles is presented. These π‐extended benzophosphole oxides exhibit interesting photophysical and electrochemical properties. Abstract Herein, we present a radical cascade addition cyclization sequence to access quinoline‐based ...
