An unprecedented Csp3-H imination reaction using arylazo sulfones as the readily accessible and stable N source is reported. The synthetic virtues are demonstrated through mild conditions, simple operation, good air compatibility, functional group tolerance, well suitability for gram-scale reaction. resulting imines can be further converted to α-amino acids. presented results shed light on an unusual usage of will inspire novel experimental design by source.

Abstract The synthesis of β‐lactam scaffolds is paramount importance due to their extensive applications in pharmaceuticals, particularly as antibiotics. Visible light photocatalysis has emerged a revolutionary approach this domain, providing sustainable and efficient pathway for construction. In review, we meticulously discuss the recent developments photocatalysed frameworks. A key focus Staudinger reaction, traditionally cornerstone synthesis, its adaptation visible photocatalysis. We explore mechanistic intricacies reaction under photochemical conditions, along with other pivotal cyclization strategies enabled by light. By illuminating novel photocatalytic routes β‐lactams, review provides thorough understanding state‐of‐the‐art techniques sets stage future innovations green these critical compounds.

A convenient method was developed for the preparation of thiolated compounds via a DBU-catalyzed aerobic cross-dehydrogenative coupling (CDC) reaction. The established protocol is environmentally friendly and operationally simple. Substrates like (hetero)aryl acetates, ketones, indoles could be transformed into corresponding products in moderate to high yields further applied bioactive prefunctionalization-free manner.
