実験手順

According to WO2010008493A2, Pneumocandin B0 as the starting material reacts with 4-methoxy thiophenol, the resulting product is protected by phenyl borate, the amide group in Pneumocandin B0 is reduced to amine group under the condition of dehydration by 3A molecular sieve, and then the resulting product reacts with ethylenediamine to obtain caspofungin.
