5-Exo-dig aminocylization/hydroxyfluorination of propargylic carbamates
Arcadi, Antonio,Chiarini, Marco,Del Vecchio, Luana,Marinelli, Fabio
, p. 1 - 13 (2018)
The unprecedented annulation/hydroxyfluorination of propargylic carbamates to give 4-fluoromethyl-4-hydroxy-oxazolidinones was investigated. The reaction was effectively promoted by NaHCO3 and/or silver catalysis. The peculiar behavior of propa
