Abstract
Process for the preparation of new 5-nitrofuryl derivatives, essentially 5-nitro-2-furfurylidenaminooxazolidinones of the general formula i ** (see formula) ** In which A means an alkylene group with 2 or 3 carbon atoms and R means a hydrogen atom, an aliphatic hydrocarbon radical with 1 to 9 carbon atoms, a radical of cycloaliphatic hydrocarbon with 3 to 9 carbon atoms or an alkoxyalkyl group with 2 to 9 carbon atoms, wherein the number of carbon existing jointly in groups a and r does not exceed that of 11, Characterized in that the corresponding oxazolidinone compound of the general formula ii is nitrated ** (see formula) ** In which A and r have the siginfication indicated above.
