CHEMOTHERAPEUTIC STUDIES IN THE THIOPHENE SERIES: I. THE SYNTHESIS OF 2-SULPHANILAMIDO-THIOPHENE
, 1941 A method is described for the synthesis of (1-acetylaminobenzene-4-sulphonamido)-2-thiophene and of (1-aminobenzene-4-sulphonamido)-2-thiophene, also called 2-sulphanilamido-thiophene. The acute toxicity of the above compounds has been determined and an

Advanced Intelligent Discovery, EarlyView.Two‐photon polymerization enables high‐resolution microfabrication, but performing alignment when printing multiple structures is difficult. Here, we present a fast, robust, and open‐source protocol for automated alignment on Nanoscribe systems. Achieving ≈0.4 μm accuracy in under 5 s, our protocol reduces time and error in multimaterial printing. This

Thiophene-Based Ligands for Specific Assignment of Distinct Aβ Pathologies in Alzheimer's Disease
Aggregated species of amyloid-β (Aβ) are one of the pathological hallmarks in Alzheimer’s disease (AD), and ligands that selectively target different Aβ deposits are of great interest.

Catalytic Enantioselective Intramolecular Aza‐Michael Addition to α,β‐Unsaturated Esters
Angewandte Chemie, EarlyView.A general method for accessing enantioenriched saturated N‐heterocycles via a catalytic enantioselective intramolecular aza‐Michael reaction to α,β‐unsaturated esters is described. A superbasic bifunctional iminophosphorane (BIMP) catalyst was key to enabling reactivity of the high pKa sulfonamide pronucleophile, whilst delivering good to excellent ...

Advanced Intelligent Discovery, EarlyView.This research demonstrates that the combination of domain knowledge–based multiple regression, multi‐objective Bayesian optimization, and generative models is a suitable prediction tool for candidates of high refractive index polymers, even with the constraints in the model trained on limited data. The experimental validation can reproduce the proposed

Transition Metal‐Free Heteroarene Insertion Into C─C Bonds of Benzocyclobutenones
Angewandte Chemie, EarlyView.A transition metal‐free insertion of five‐membered heteroarenes into the C─C bonds of benzocyclobutenones has been achieved under mild and operationally simple conditions. This method provides an efficient and modular approach to access fused partially saturated hetero‐polycyclic scaffolds that exist in many bioactive molecules.
