A photomediated protocol giving facile access to substituted β-lactam and β-lactones is presented. The method realizes, for the first time, the use of the Zimmerman-O'Connell-Griffin (ZOG) rearrangement in [2 + 2] cycloaddition. Products are obtained in high yield with excellent diastereoselectivity under visible light irradiation and under mild reaction conditions.

Clinical Features: Sickle cell patients may develop a multitude of antibodies and experience life-threatening events with transfusion such as hyperhemolysis syndrome or delayed hemolytic transfusion reaction. Further transfusion may not be possible in such cases.

Therapeutic Challenge: When conventional blood products are not available for transfusion yet the patient requires additional oxygen-carrying support, artificial oxygen carriers may be required.

Taking the natural product cerbinal as the lead compound, 30 novel 5-aryl-cyclopenta[]pyridine derivatives were designed and synthesized based on the previous bioactivity studies of the cyclopenta[]pyridines. The modification of the position-5 of compound was achieved by amination, bromination, and cross coupling using cerbinal as the raw material. The results of the bioactivity tests demonstrated that partial compounds exhibited superior activity against plant viruses compared to compound .

Amino alcohols are vital in natural products, pharmaceuticals and agrochemicals, and as key building blocks for various applications. Traditional synthesis methods often rely on polar bond retrosynthetic analysis, requiring extensive protecting group manipulations that complicate direct access. Here we show a streamlined approach using a serine-derived chiral carboxylic acid in stereoselective electrocatalytic decarboxylative transformations, enabling efficient access to enantiopure amino alcohols.

Sulfur-containing units are fundamental components widely found in bioactive compounds, prompting notable efforts toward developing synthetic methodologies for incorporating sulfur functionality into organic precursors. The synthesis of sulfinate esters and sulfinamides has garnered significant interest owing to their immense potential for applications, especially in drug development. However, most existing synthetic protocols suffer from some limitations.
