Tandem catalytic aromatization of volatile fatty acids [PDF]

, 2020
The transition towards a circular economy requires closing the carbon loop, e.g. by the development of new synthesis routes to valuable intermediates and products from organic-rich waste streams.

Stereoselective Biotransformation: Transfer of Learning to Advance Drug Metabolism and Biocatalysis

Angewandte Chemie, EarlyView.
Understanding stereoselective biotransformations has implications for predicting drug disposition and response and may also inspire novel biocatalytic and biomimetic strategies to address challenges in metabolite and API synthesis. ABSTRACT Chirality is an important determinant of drug action, as enantiomers can exhibit markedly different ...

A Neutral “Masked” Diborene and Its Reactivity Toward Metal‐Free Pyridine Homocoupling

Angewandte Chemie, EarlyView.
An unprecedented neutral “masked” diborene, formed via intramolecular arene dearomatization of an N‐heterocyclic imine‐supported free diborene, can be photochemically released to regenerate the highly reactive triplet diborene intermediate. Computational analysis elucidates the bonding situation of the hitherto elusive free diborene species, and the ...

Increase in the Bioactive Potential of Olive Pomace Oil after Ultrasound-Assisted Maceration

Foods, 2023
Olive pomace oil is obtained when a mixture of olive pomace and residual water is subjected to a second centrifugation. This oil has small amounts of phenolic and volatile compounds compared with extra-virgin olive oil.

A Nonbenzenoid Nanographene Horse Saddle With Four Pentagon–Octagon Pairs

Angewandte Chemie, EarlyView.
Horse‐saddle molecule: We report herein the design and synthesis of an unprecedented saddle‐shaped non‐benzenoid Nanographene featuring a fused four‐pair pentagon–octagon core. The horse‐saddle structure of HN1 is determined by single‐crystal X‐ray diffraction.

Pyridine C─N Transposition via Cycloaddition–Cycloreversion

Angewandte Chemie, EarlyView.
Transposition of pyridine nitrogen from the 4‐ to the 3‐position is described using two open and shut sequences: a nucleophile addition ring‐open ring‐closure, followed by a nitrile Diels–Alder cycloaddition cycloreversion. The nitrogen swap is particularly effective for tertiary alkyl substituents, transforming easily accessible para‐alkylated ...
