Application
it is an excellent silylation reagent, which can replace the active hydrogen atom in organic molecules with trimethylsilicon atom group. This product is β- Lactam is the most ideal silanized protective agent in the synthesis of antibiotics. Taking the hemisynthesis of cephalosporin IV as an example, using only BSU to participate in the reaction can make the reaction conditions extremely mild, have fewer side reactions, and the yield is 2-3 times higher than that of other methods. It has great practical value in the industrial production of antibiotics.
