Total Synthesis of Arylnaphthalene Lignans through a Photochemical Key Step
European Journal of Organic Chemistry, Volume 26, Issue 1, January 2, 2023., 2023 The total syntheses of arylnaphthalene lignans (ANL) Vitrofolal E (1), Noralashinol C (2), and Ternifoliuslignan E (3) are described. These natural products have in common a missing substituent in 2‐position of the naphthalene skeleton (2H‐ANL). The key step of the syntheses is the Photo‐Dehydro‐Diels‐Alder (PDDA) reaction between arylalkyne moieties ...

The emerging role of dark berry polyphenols in human health and nutrition
Food Frontiers, Volume 3, Issue 1, Page 3-27, March 2022., 2022 Several species of dark berries have become available for general consumption which contain high levels of polyphenols. This review examines the available chemical compositions of several dark berries and their health effects, and the potential of these often under studied species to suggest areas for future research. Abstract Dark berry fruits are one

Functional implications of bound phenolic compounds and phenolics–food interaction: A review
Comprehensive Reviews in Food Science and Food Safety, Volume 21, Issue 2, Page 811-842, March 2022., 2022 Abstract Sizeable scientific evidence indicates the health benefits related to phenolic compounds and dietary fiber. Various phenolic compounds‐rich foods or ingredients are also rich in dietary fiber, and these two health components may interrelate via noncovalent (reversible) and covalent (mostly irreversible) interactions.

Selective Oxidation of Arabinose on Gold Catalysts: Process Design and Techno‐economic Assessment
Chemical Engineering &Technology, Volume 44, Issue 10, Page 1775-1782, October 2021., 2021 Process design and techno‐economic assessment was done for selective arabinose oxidation on a supported gold catalyst. The profitability is strongly influenced by the operating costs, which are highly dependent on the arabinose feedstock. The feedstock price has an important impact on the performance requiring efficient extraction of hemicellulose from
