Process for making functionalized oxazolidinone compounds

Abstract

The subject invention involves process for making fuctionalized oxazolidinones having structure (1) wherein: (a) R1 and R2 are each independently selected from hydrogen, alkyl, aryl and heterocycle, or R1 and R2 are attached to form a cycloalkyl, aryl or heterocyclic ring; (b) R3 is selected from primary and secondary alkly (—R6), —SO2—R4, and —C(O)NH—R5; (c) R4 is aryl; and (d) R5 is alkyl or aryl; the process comprising a reaction step carried out in a reaction mixture, wherein an oxazolidinone is reacted with an electrophile selected from R6-Br, R6-I, R4-SO2Cl, and R5-NCO; the reaction mixture comprising a non-protic and non-oxidizing solvent and potassium fluoride on alumina; and without the presence of a substantial amount of a strong base in the reaction mixture. The subject invention also involves libraries of functionalized oxazolidinone compounds and their preparation using such processes.
