ISSN: 0018-019XKeywords: Chemistry ; Organic ChemistrySource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyNotes: Methanolysis and ethanolysis of 1-chloro-3-chloromethyl-4-methyl-isoquinoline yield respectively 3-methoxymethyl-4-methyl-isocarbostyril and 3-ethoxymethyl-4-methyl-isocarbostyril as main products, together with some 3-chloromethyl-4-methyl-isocarbostyril. By analogous reactions, 1-chloro-4-chloromethyl-3-methyl-isoquinoline yields 4-methoxymethyl-3-methyl-isocarbostyril and 4-ethoxymethyl-3-methyl-isocarbostyril.Type of Medium: Electronic ResourceURL: -

Published 1966Staff ViewISSN: 0018-019XKeywords: Chemistry ; Organic ChemistrySource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyNotes: 1-(5-Nitro-2-thiazolyl)-2-imidazolidinone is synthesized from 2-amino-5-nitro-thiazole and 2-chloroethyl-isocyanate. The structure of this new potent schistosomicide is established by acid and alkaline degradation as well as by synthesis starting from 2-imidazolidinone. A number of derivatives of 1-(5-nitro-2-thiazolyl)-2-imidazolidinone are reported.Additional Material: 3 Tab.Type of Medium: Electronic ResourceURL: -

ISSN: 0018-019XKeywords: Chemistry ; Organic ChemistrySource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyNotes: The products resulting from condensation of veratrole and α,β-unsaturated acids in polyphosphoric acid are the corresponding 1-indanones. With pyrogallol trimethyl ether and with resorcinol dimethyl ether the nature of the products of these condensations varies according to the α,β-unsaturated acid employed. Usually it will be a phenyl vinyl ketone, which agrees with the results given in the literature for the reaction with anisole. The ability of the various aromatic ethers to form indanones by this condensation is discussed on the basis of the π-electron density in the different positions of the aromatic ethers.Additional Material: 3 Ill.Type of Medium: Electronic ResourceURL: -

ISSN: 0018-019XKeywords: Chemistry ; Organic ChemistrySource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyNotes: The condensation of cinnamic acid and veratrole, yielding 5, 6-dimethoxy-1-indanone, takes place with acylation as the first step (e.g. with 3′, 4′-dimethoxy-chalcone as intermediate), followed by alkylation. If the methyl ester of cinnamic acid is employed instead of the acid itself, the order of the steps is reversed (e.g. with methyl β-(3,4-dimethoxyphenyl)-β-phenyl-propionate as the main intermediate).Additional Material: 2 Ill.Type of Medium: Electronic ResourceURL: -

ISSN: 0018-019XKeywords: Chemistry ; Organic ChemistrySource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyNotes: The reaction of veratrole with cinnamoyl chloride and with crotonoyl chloride in the presence of aluminium chloride yielded phenyl vinyl ketones. In the case of cinnamic acid, the preparation of the acid chloride as well as the FRIEDEL-CRAFTS condensation could be carried out in one step, without isolation and purification of the chloride. Application of this procedure to acrylic acid yielded as sole product a β-chloro-ketone derivative, whereas with crotonic acid a mixture of the corresponding phenyl vinyl ketone and β-chloro-ketone was obtained. Again a different result was obtained in the condensation of methacryloyl chloride, which yielded a 1-indanone instead of an acyclic ketone.Type of Medium: Electronic ResourceURL: -

ISSN: 0018-019XKeywords: Chemistry ; Organic ChemistrySource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyNotes: On reinvestigation of the reaction of wet phosphorus oxychloride with α,α-dimethylhomophthalimide, 1-chloro-3-chloromethyl-4-methyl-isoquinoline and 1-chloro-4-chloromethyl-3-methyl-isoquinoline were isolated as the main products (aside from some substances resulting from a redox disproportionation). The production of these two substances can be rationalized by assuming a mechanism in which the rearrangement product is a protonated derivative of 3,4-dimethylene-3, 4-dihydroisoquinoline. With α, α-diethyl-homophthalimide the only isolated product was a derivative of 1-chloro-3, 4-diethyl-isoquinoline, with a chlorine atom in β-position of one of the ethyl groups, while with α-methyl-α-benzyl-homophthalimide the isolated product was 1,3-dichloro-4-methyl-isoquinoline, i.e. elimination had taken place instead of rearrangement. Also these results are in agreement with the proposed mechanism.Additional Material: 3 Ill.Type of Medium: Electronic ResourceURL:
