Interaction of hydroxy acetophenones and their derivatives and thionyl chloride in presence of finely divided copper - Part IV. Preparation of 3:3′-diacetyl-4:4′-dihydroxy-6:6′-dibenzyloxy-diphenyl thioether and its derivatives
Volume 69 Issue 2 February 1969 pp 94-102
Volume 82 Issue 6 December 1975 pp 211-216
The O-cyanoethylation of 7-hydroxy-3, 4-cyclopenteno- and 7-hydroxy-3, 4-cyclohexeno-coumarins followed by hydrolysis and cyclisation of the resulting acids, affords α-pyronochromanones whose structures have been established by spectral data and the formation of 2, 4-DNP derivatives.
Volume 84 Issue 2 August 1976 pp 85-90
The reaction of hexachloropropene with hydroxy-coumarins and chromones has been utilized to synthesise dichloro-benzodipyrandiones. The structures of the latter have been deduced from their spectral-analytical data. The reaction with 4-hydroxy-coumarin derivatives affords dichloropyrano-benzpyrandiones.
Volume 84 Issue 4 October 1976 pp 139-143
The C-cyanoethylation of the methyl and ethyl ethers of dimethylphenols has been carried out with acrylonitrile in the presence of anhydrous AlCl3 to furnish propionitrile derivatives. The latter on hydrolysis to the corresponding propionic acids followed by cyclization with PPA afforded the appropriate indanones, whose structures have been established on the basis of spectral data and by the formation of 2, 4-DNP derivatives.
Volume 85 Issue 3 March 1977 pp 115-124
Cyanoethylation of some dimethyl- and trimethylphenols in acidic and basic media has been investigated. The cyanoethyl derivatives obtained were hydrolysed to the corresponding acids which on cyclisation with PPA afforded either dihydrocoumarin or chromanone whose structures were assigned on the basis of chemical and spectral evidence.
Volume 85 Issue 4 April 1977 pp 236-241
The reaction of hexachloropropene with dihydroxy aryl aldehydes, ketones and acids has been explored to synthesise substituted 3, 4-dichlorocoumarins. The structures of the latter have been deduced from their spectral-analytical data.
Volume 85 Issue 6 June 1977 pp 524-530
The reaction of hydroxycoumarins, flavones, isoflavones and chromones with α, β-unsaturated acids, in the presence of PPA has been found to give a number of compounds whose structures have been elucidated on the basis of spectral data and the formation of 2, 4-DNP derivatives.
