抄録

Following compounds were synthesized as the derivatives of coumarin- and 6-nitro-coumarin-3-carboxylic acid:
1) Isoamyl coumarin-, methyl 6-nitrocoumarin-, and ethyl 6-nitrocoumarin-3-carboxylates (Table I).
2) Anilide (I), anisidide (II), and phenetidide (III) of coumarin-3-carboxylic acid, and anilide (V), p-anisidide (VI), and p-phenetidide (VII) of 6-nitrocoumarin-3-carboxylic acid (Table II).
3) Aniline (IX), anisidine (X), p-phenetidine (XI), and ethyl p-aminobenzoate (XII) salts of 6-nitrocoumarin-3-carboxylic acid (Table II).
