WebIn addition to quercetin, onions contain the phytochemicals known as disulfides, trisulfides, cepaene, and vinyl dithiins. These compounds have a variety of health-functional properties, including demonstrated in vitro anticancer and anti-microbial activities. Onions are also a source of vitamin C, potassium, dietary fiber and folic acid. WebJul 7, 1995 · The first structure-activity study involving the 1,2-dithiin class of compounds (1,2-dithiacyclohexadienes) is herein reported. A series of 3,6-disubstituted 1,2-dithiins was synthesized from dithiins 1d and 1e and evaluated as antifungal agents. A new and versatile synthesis of dithiins 1d and 1e is reported which is amenable to scale-up at ...

WebAug 12, 2010 · Synthetic routes to 1,4-dithiins have been explored more thoroughly than those to the 1,4-dioxin and 1,4-oxathiin ring systems. The parent compound is obtained in 47–60% yield by vapour-phase dealkoxylation of 2,5-dialkoxy-1,4-dithianes over alumina at 260–265 °C, and this type of approach can also be used to prepare 2,5-dimethyl-1,4-dithiin. things to say after farting
