Abstract
Process for the production of coumarin and coumarinimide compounds, of formula I, **(See formula)** wherein R1 signifies an unsubstituted or substituted alkyl or phenyl radical, said alkyl radical containing from 1 to 6 carbon atoms, R2 signifying a hydrogen atom or an unsubstituted or substituted alkyl or phenyl radical, said alkyl radical containing 1 to 6 carbon atoms, or R1 and R2, together with the nitrogen atom to which they are attached, form a 5- or 6-membered heterocyclic ring, saturated, partially saturated or unsaturated, means a hydrogen atom, an acyl radical, an organic ester radical, or an unsubstituted or substituted alkyl or phenyl radical, said acyl and alkyl radicals containing from 1 to 6 carbon atoms, R4 and R5, which may be the same or different, each signify an atom of hydrogen, an acyl radical, an organic acid ester radical, or an unsubstituted or substituted alkyl, phenyl, or heterocyclic radical, where the alkyl radical contains from 1 to 6 carbon atoms, the acyl radical contains from 1 to 6 atoms carbon, and the heterocyclic radical has 5 or 6 members, being saturated, partially saturated or unsaturated, or R4 and R5, together with the nitrogen atom to which they are attached, form a 5- or 6-membered heterocyclic ring, without substituted or substituted, saturated, partially saturated or unsaturated, and X means an oxygen atom or is = NH; characterized in that a compound of formula II is condensed, **(See formula)** wherein R1 and R2 are as defined above, with a compound of formula III, **(See formula)** wherein R3, R4 and R5 are as defined above, to provide a compound of the formula **(See formula)** wherein R1, R2, R3, R4 and R5 are as defined above, and, in case a compound of formula I is desired to be obtained, where X stands for an oxygen atom, the compound is hydrolyzed of formula Ib, as defined above, to provide a compound of formula Ic, **(See formula)** wherein R1, R2, R3, R4 and R5 are as defined above.
