Oxidation of acyclic alkenes and allyl and benzyl ethers with DIB/t-BuOOH/Mg(OAc)
, 2012 Oxidation of (11Z)-1′,2′-didehydrostemofoline with DIB/TBHP/Mg(OAc)2·4H2O resulted in oxidative cleavage of the C-11-C-12 double bond instead of the desired allylic oxidation of the 1-butenyl side chain. Stemofoline gave a similar result.

The Chemical Record, EarlyView.Nickel foam—one material, two faces, and several versatile roles depending on electrolytic conditions. For more than 50 years, nickel foam electrodes have served in electrosynthesis as powerful and readily available electrode materials. Due to their inexpensive nature and easy handling, they have been widely employed.

Novel approaches for drug development against chronic primary pain: A systematic review
British Journal of Pharmacology, EarlyView.Abstract Chronic primary pain (CPP) persisting for more than 3 months, associated with significant emotional distress without any known underlying cause, is an unmet medical need. Traditional or adjuvant analgesics do not provide satisfactory pain relief for a great proportion of these patients.

Advances in organic UV filters for sunscreens over the past decade
Photochemistry and Photobiology, EarlyView.Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...
