Synthesis of p-aminobenzoic acid diamides based on 4-(4-methoxyphenyl)tetrahydro-2H-pyran-4-carboxylic acid and [4-(4-methoxyphenyl)tetrahydro-2H-pyran-4-yl]methylamine
摘要:
Reaction of 4-(4-methoxyphenyl)tetrahydro-2H-pyran-4-carboxyl chloride with anesthesin followed by hydrolysis of the formed ester has afforded 4-[4-(4-methoxyphenyl)tetrahydro-2H-pyran-4-carbonylamino]benzoic acid. The acid chloride has been used for acylation of various amines to yield the corresponding diamides. Reaction of [4-(4-methoxyphenyl)tetrahydro-2H-pyran-4-yl]methylamine with chlorides of N-substituted p-aminobenzoic acids has led to formation of diamides.

4-(4-methoxyphenyl)tetrahydro-2H-pyran-4-carbonyl chloride with hydrazine hydrate, furan-2- and 2,5-dimethylfuran-2carbohydrazides gave disubstituted hydrazides, whose cyclization formed symmetrical and unsymmetrical 2,5-disubstituted 1,3,4-oxadiazoles. Ethyl 4-[4-(4-methoxyphenyl)-tetrahydro-2H-pyran-4-carboxamido]benzoate was reacted with hydrazine to obtain N-[4-(hydrazinocarbonyl)-phenyl]-4-(4-methoxp

Reaction of 4-(1,4-benzodioxan-2-yl)thiazol-2-amine with acid chlorides afforded N-substituted amides which further were reduced into the corresponding amines. A new method was developed of preparation of 2-acetyl-1,4-benzodioxane, the initial compound in the synthesis of thiazolylbenzodioxane and numerous derivatives of this series. The adreno- and sympatholytic as well as antihypoxic effect of the obtained biheterocyclic 1,4-benzodioxane derivatives were investigated.
