Thiamphenicol synthese
Thiamphenicol (also known as thiophenicol and dextrosulphenidol) is an antibiotic. It is the methyl-sulfonyl analogue of chloramphenicol and has a similar spectrum of activity, but is 2.5 to 5 times as potent. Like chloramphenicol, it is insoluble in water, but highly soluble in lipids. It is used in many countries as a veterinary antibiotic, but is available in China, Morocco and Italy for use in hum… Web17 Aug 2024 · In this paper, an expeditious and efficient continuous-flow process is reported for the synthesis of syn-2-amino-1,3-diol. The starting material syn-2-nitro-1,3-diol reacts with hydrogen gas in a micro fixed-bed reactor packed with a Raney Ni catalyst to provide syn-2-amino-1,3-diol in 93% isolated yield. The reaction time in the flow system was …
