(R)‐Propylene carbonate is an important intermediate in the synthesis of tenofovir pro‐drugs such as tenofovir alafenamide fumarate (TAF) and tenofovir diisoproyl fumarate (TDF). Independent of the pro‐drug type, tenofovir presents a chiral secondary hydroxy derivative, which can be obtained directly from (R)‐propylene carbonate. Herein, we report our chemo‐enzymatic continuous‐flow strategy towards (R)‐propylene carbonate starting from a very cheap and renewable raw material, glycerol. We were able to synthesize (R)‐propylene carbonate in seven continuous‐flow steps, starting from glycerol, in good‐to‐excellent yields (66–93 %) and excellent selectivity (E > 200).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
