    摘要: Processes are described for preparing 42-pegylated rapamycins including reacting a rapamycin with an acylating agent in the presence of a lipase to form an acylated rapamycin and reacting the acylated rapamycin with a methoxy poly(ethylene glycol) derivative in the presence of a base. Also described are processes for preparing 32-pegylated tacrolimus and/or ascomycin using these steps.
