摘要:The present invention provides a scalable two-step synthesis of molnupiravir. The reaction sequence involves the use of commercially easily available cytidine (1), and molnupiravir is formed through direct hydroxy amination of the cytidine followed by esterification of the primary alcohol without protecting dihydroxy groups (vicinal diols) i.e. without formation of acetonide.
