Abstract
Procedure for the preparation of 5-nitrofuryl derivatives of the general formula I **(See formula)** in which R1 signifies an unsubstituted alkyl group, containing 1 to 5 carbon atoms; or a carbalkoxy group containing in the alkyl part of 1 to 5 carbon atoms, and R2 stands for hydrogen; an alkyl group containing from 1 to 5 carbon atoms, which may be unsubstituted or in which one, several or all of the hydrogen atoms may be replaced by chlorine or bromine atoms; or a cycloalkyl group containing on the carbocyclic ring from 5 to 7 carbon atoms; an aralkyl group containing up to 12 carbon atoms; or an alkenyl group containing from 2 to 4 carbon atoms, characterized in that a compound of the general formula II is reacted **(See formula)** in which R1 has the indicated significance, with a carbonic acid derivative, R2COX or (R2CO) 2O, where R2 has the indicated significance and X means a bidroxy group, an amino group or the OR3 group, where R3 means the alkyl group or alkenyl containing 1 to 3 carbon atoms, and a compound obtained from the general formula III **(See formula)** in which R1 and R2 have the significance indicated under formula I, cyclized without isolate.
