Stereoselectivity in the reduction of bicyclic tetramates [PDF]

, 2016
The reduction of bicyclic tetramates can be achieved with high levels of diastereocontrol, but small changes in the substitution of the bicyclic lactam system can lead to changes in the steric bias of the concave/convex system.

In Situ Lipoprotein‐seeking Dye for in Vivo Real‐Time Imaging of Lipid Dysregulation Diseases

Advanced Science, Volume 13, Issue 19, 2 April 2026.
This study develops lipoprotein‐seeking NIR‐II dyes that specifically bind circulating lipoproteins. These dyes form ultra‐stable complexes with endogenous lipoprotein, enabling real‐time, high‐contrast imaging of fatty liver and atherosclerotic plaques. Tunable binding kinetics allow customized imaging windows.

Synthesis and bioactivity of fused- and spiro-β-lactone-lactam systems [PDF]

, 1916
An investigation of the formation of fused- and spiro-β-lactone annulate to γ-lactams has shown that the fused systems are formed preferentially, under standard conditions, but that spiro systems are accessible only when the formation of the fused system

Synthesis of a-chlorolactams by cyanoborohydride-mediated radical cyclization of trichloroacetamides [PDF]

, 2019
A cyanoborohydride-promoted radical cyclization methodology has been developed to access α-chlorolactams in a simple and efficient way, using NaBH3CN and trichloroacetamides easily available from allylic and homoallylic secondary amines. This methodology

Optical Density of Perovskite Films as a Novel Parameter in Statistical Modeling for Perovskite Solar Cells

physica status solidi (RRL) – Rapid Research Letters, Volume 20, Issue 4, April 2026.
A data‐driven approach is applied to analyze blade‐coated perovskite films, revealing how synthesis and processing variables influence thickness and optical properties. A compact UV–vis‐based descriptor reduces complex absorption data into key metrics, enabling efficient exploration of high‐dimensional design spaces and offering a practical pathway to ...

Synthesis and Biological Profile of Substituted Pyrrolidinyl Carboxamides for Acyl‐ACP Thioesterase Inhibition

European Journal of Organic Chemistry, Volume 29, Issue 12, 23 March 2026.
The work outlined herein covers a series of novel herbicidal lead structures that possess a pyrrolidinyl pyrazole carboxamide scaffold as a key structural feature, carrying further substituted benzyl side chains. Based on scaffold hopping approaches from known fungicidal and herbicidal compounds and utilizing an optimized synthetic approach, a broader ...
