Continuous flow chemistry: a discovery tool for new chemical reactivity patterns [PDF]

open access: yes, 2014
Continuous flow chemistry as a process intensification tool is well known. However, its ability to enable chemists to perform reactions which are not possible in batch is less well studied or understood. Here we present an example, where a new reactivity

Altered Auditory Maturation in Fragile X Syndrome and Its Involvement in Audiogenic Seizure Susceptibility

open access: yesAutism Research, Volume 19, Issue 1, January 2026.
ABSTRACT Auditory hypersensitivity is a prominent symptom in Fragile X syndrome (FXS), the most prevalent monogenic cause of autism and intellectual disability. FXS arises through the loss of the protein encoded by the FMR1 (Fragile X Messenger Ribonucleoprotein 1) gene, FMRP, required for normal neural circuit excitability.

Synthesis of Novel BINOL Analogs: 3,3′‐Dicarbonyl‐1,1′‐binaphthyl‐4,4′‐diols as Precursors to the Uncharted 5,5′‐Binaphtho[2,1‐d]isoxazole

open access: yesEuropean Journal of Organic Chemistry, Volume 28, Issue 45, December 10, 2025.
The parent 5,5′‐binaphtho[2,1‐d]isoxazole and its 3,3′‐dimethyl and 3,3′‐diphenyl derivatives are synthesized via condensation of the respective dicarbonyl compounds with hydroxylamine, followed by cyclodehydration of the resulting dioximes. The dicarbonyl precursors are obtained through 4‐ or 6‐step sequences from 1‐naphthol or 1‐naphthaldehyde ...
