The presence of pollutants in aquatic environments is causing severe health effects on both humans and animals. To address this issue, it has become crucial to develop more efficient environmentally friendly photocatalysts for the removal persistent pollutant mixtures from water. In context, containing than two bismuth-based materials have rarely been explored water remediation. With mind, we propose an innovative ternary composite, BiOCl-1/Bi12O17Cl2/Bi2O3, as a potentially sustainable...

Naturally occurring nootkatone, with reported insecticidal and acaricidal properties, has been used as a lead to generate molecular diversity and, consequently, new insect antifeedant ixodicidal compounds. A total of 22 derivatives were generated by subjecting this molecule several reactions including dehydrogenation the iodine/DMSO system, oxidation SeO2, epoxidation mCPBA, or carbon homologations α-carbonyl position TMSOTf (trimethylsilyl trifluoromethanesulfonate) followed Rubottom Dess...

The system I2/dimethyl sulfoxide mediates the one-step transformation of α-isopropylidene ketones into furan rings following a biomimetic approach. This methodology has been used for synthesis terpene furans such as mintfurane, curzerene, atractylon, and isoatractylon, all them possessing interesting biological activities. linderazulene directly from 4,5-epoxygermacrone via cascade reaction shows potential this protocol. Additionally, compound proved to show significant ixodicidal activity.

We have proven that the biomimetic-like synthesis of cannabinoids from citral and corresponding phenolic counterpart may well be carried out using water as a solvent. The influence different additives such surfactants was also analyzed. Rationalization reaction mode regiochemistry processes were provided in terms "on water" "in reactions. same reactions conducted organic media Ga(III) salts catalysts. Worthy being underlined, an unprecedented formal [2+2+2] process found to occur between two...

Currently, the use of synthetic pesticides is main method plant protection applied in agri- and horticulture. However, its excessive leads to development pesticide resistance, a contamination environment, toxicity non-target organisms, risks for human health. With ultimate aim contributing develop more sustainable pest management, we used natural product germacrone (compound1), reported possess significant insecticidal activity, as starting material generation molecular diversity (2-24)....
