Optimized Conditions for Passerini-Smiles Reactions and Applications to Benzoxazinone Syntheses

Molecules, 2016
Initial conditions disclosed for the Passerini-Smiles reaction are associated with a lack of efficiency that has prevented chemists from using it since its discovery.

Unconventional Passerini Reaction toward α-Aminoxy-amides

Organic Letters, 2016
The Passerini multicomponent reaction (P-3CR) toward the one-step synthesis of α-aminoxy-amide, by employing for the first time a N-hydroxamic acid component, has been reported. The sonication-accelerated, catalyst-free, simple, fast, and highly efficient Passerini reaction is used for the synthesis of diverse α-aminoxy-amides.

A straightforward approach towards combined α-amino and α-hydroxy acids based on Passerini reactions

Beilstein Journal of Organic Chemistry, 2011
Complex amino acids with an α-acyloxycarbonyl functionality in the side chain are easily available through epoxide opening by chelated enolates and subsequent oxidation/Passerini reaction. This protocol works with both, aldehyde and ketone intermediates,

Fabrication of Composite Cathode for All‐Solid‐State Sodium Batteries

Advanced Energy Materials, EarlyView.
The design of composite cathodes for all‐solid‐state sodium batteries must address three critical challenges—interfacial side reactions, interfacial delamination, and highly tortuous transport pathways. This work outlines structural and interfacial strategies to optimize ion transport and mechanical stability, enabling durable, and high‐performance ...

Spontaneous uterine rupture after myomectomy in patients during pregnancy: Clinical cases in a single university center

International Journal of Gynecology &Obstetrics, Volume 173, Issue 1, Page 24-34, April 2026.
Abstract Uterine rupture is an infrequent yet sometimes fatal complication of a subsequent vaginal birth attempt following a previous uterine surgery. We have chosen to write about spontaneous uterine ruptures following myomectomy due to the scarcity of data on this subject, stemming from the limited number of reported cases.

Silent Partners in the Mill: Unveiling the Role of Additives in Mechanochemical Synthesis

Chemistry – A European Journal, Volume 32, Issue 9, 2 March 2026.
Mechanochemistry offers a sustainable, solvent‐free alternative to traditional synthesis, often enhanced by additives in a process known as additive‐assisted grinding. This review discusses how various additives, including liquids, ionic solids, and advanced materials like ionic liquids and piezoelectric compounds, improve reaction efficiency ...
