Process Development for A Novel Pleuromutilin-Derived Antibiotic
摘要:
A scalable synthesis of a novel pleuromutilin-based antibiotic is reported. The synthesis features the scale-up of an interesting skeletal rearrangement of the pleuromutilin core and isolation. of a highly purified product despite starting with relatively impure pleuromutilin. The use of Design of Experiment (DoE) and Principal Component Analysis (PCA) tools to achieve these goals is also discussed. Furthermore, the novel coupling of a carbamate and N-acyl-imidazole to produce the imidodicarbonate portion of the target molecule is described.
