Abstract
4-Hydroxycoumarins and their 1-thio analogues of the general formula: <FORM:0773468/IV(b)/1> (wherein X is O or S, R is alkyl, alkoxyalkyl, aryloxyalkyl, aryl or alkylmercaptoalkyl, aralkyl, aryl, arylaryl, or aralkylaryl wherein aromatic nuclei can be substituted by halogen, alkyl, alkoxy or nitro groups, and Ar is o-arylene aryl-o-arylene or aralkyl-o-arylene wherein aromatic nuclei can be substituted by halogen, alkyl or alkoxy groups) are prepared by heating to at least 240 DEG C., preferably 300 DEG C., a -substituted malonic acid diaryl esters of formula Ar1XCOCHRCOXAr1, wherein Ar1 represents the aryl, arylaryl or aralkylaryl radical corresponding to Ar, having a hydrogen atom in at least one o-position with regard to X. In examples: (1) isoamyl malonic acid diphenyl ester is heated 90 minutes at 300 DEG C. in a flask fitted with a wide sloping tube, phenol distils off, the residue is extracted with sodium hydroxide solution and 3-isoamyl-4-hydroxycoumarin precipitated with HCl; similarly prepared are 3 - methyl -, ethyl -, n - propyl -, isopropyl -, n - butyl -, n - amyl -, isoamyl, n-hexyl -, phenyl -, and benzyl - 4 - hydroxycoumarin; (2) benzylmalonic acid bis-(p-benzylphenyl) ester is heated in a sausage flask, and then 4-benzylphenol distilled off under reduced pressure, leaving 3,6 - dibenzyl - 4 - hydroxycoumarin; (3) benzylmalonic acid bis-(p-phenylphenyl) ester is heated at 300 DEG C., and p-phenylphenol removed by steam distillation, yielding 3-benzyl-4-hydroxy-6-phenylcoumarin; (4) benzylmalonic acid bis-(o-benzyl-p-chlorophenyl) ester is heated as above and 3,8-dibenzyl - 4 - hydroxy - 6 - chlorocoumarin isolated by extraction with boiling aqueous caustic soda lye, filtration and acidification. Other starting materials specified for the cyclisation process are benzyl dithiolmalonic acid diphenyl ester, 4-chlorobenzyl malonic acid bis-p-cresyl ester, 2-methyl-benzyl malonic acid bis-4-methoxyphenyl ester, 3,4-dimethoxy-benzyl malonic acid diphenyl ester, 4-bromophenyl malonic acid diphenyl ester, 4-isopropylphenyl malonic acid diphenyl ester and 4-methoxyphenyl malonic acid diphenyl ester.
