dialkyloxy-4-methylcoumarins were successfully synthesized starting from dihydroxy-4-methylcoumarins and an alkyl bromide, butyl bromide or octyl bromide, at 1:1 molar ratio. The alkylation of 5,7-dihydroxy-4-methylcoumarin gave 5,7-dialkyloxy-4-methylcoumarin and two monoalkyloxy-4-methylcoumarins with substitution at 5 and 7 positions. For 6,7- and 7,8-dihydroxy-4-methylcoumarins, the corresponding dialkyloxy-4-methylcoumarins and only monoalkyloxy-4-methylcoumarins at the 7 position were obtained. UV absorption studies of the dihydroxy-4-methylcoumarins and their mono- and dialkyloxy products showed a red shift of the maximum absorption wavelengths compared to 4-methylcoumarins. Additionally, substitution of a hydroxyl or alkyloxy group at the 6-position caused a further red shift. The dimerization degree from decreasing of UV absorbance revealed that it depended on the substitution positions. Among all these coumarin derivatives, 5,7-dibutyloxy-4-methylcoumarin exhibited the highest dimerization degree.", "subjects" : [ { "otype" : "Classification", "mtid" : 10799, "link" : "/api/classification/10799", "label" : "Egyéb természettudományok", "published" : true, "snippet" : true } ], "keywords" : [ { "otype" : "Keyword", "mtid" : 7740, "link" : "/api/keyword/7740", "label" : "Dimerization", "published" : true, "oldId" : 7740, "snippet" : true }, { "otype" : "Keyword", "mtid" : 1677626, "link" : "/api/keyword/1677626", "label" : "monoalkyloxycoumarin", "published" : true, "snippet" : true }, { "otype" : "Keyword", "mtid" : 1677627, "link" : "/api/keyword/1677627", "label" : "dialkyloxycoumarin", "published" : true, "snippet" : true }, { "otype" : "Keyword", "mtid" : 1677628, "link" : "/api/keyword/1677628", "label" : "substitution effect", "published" : true, "snippet" : true } ], "digital" : null, "printed" : null, "sourceYear" : 2019, "foreignEdition" : true, "foreignLanguage" : true, "fullPublication" : true, "conferencePublication" : false, "nationalOrigin" : null, "missingAuthor" : false, "oaType" : "NONE", "oaCheckDate" : "2022-07-29", "oaFree" : false, "citationCount" : 0, "citationCountUnpublished" : 0, "citationCountWoOther" : 0, "independentCitCountWoOther" : 0, "doiCitationCount" : 0, "wosCitationCount" : 0, "scopusCitationCount" : 0, "independentCitationCount" : 0, "unhandledCitationCount" : 0, "citingPubCount" : 0, "independentCitingPubCount" : 0, "unhandledCitingPubCount" : 0, "citedPubCount" : 1, "citedCount" : 1, "ratings" : [ { "otype" : "SjrRating", "mtid" : 10752380, "link" : "/api/sjrrating/10752380", "label" : "sjr:Q4 (2018) Scopus - Biochemistry, Genetics and Molecular Biology (miscellaneous) CHIANG MAI JOURNAL OF SCIENCE 0125-2526", "listPos" : 196, "rankValue" : 1.0, "type" : "journal", "ratingType" : { "otype" : "RatingType", "mtid" : 10002, "link" : "/api/ratingtype/10002", "label" : "sjr", "code" : "sjr", "published" : true, "snippet" : true }, "subject" : { "otype" : "ClassificationExternal", "mtid" : 1301, "link" : "/api/classificationexternal/1301", "label" : "Scopus - Biochemistry, Genetics and Molecular Biology (miscellaneous)", "published" : true, "oldId" : 1301, "snippet" : true }, "ranking" : "Q4", "calculation" : "DIRECT", "published" : true, "snippet" : true } ], "ratingsForSort" : "Q4", "hasCitationDuplums" : false, "directInstitutesForSort" : "", "ownerAuthorCount" : 3, "ownerInstituteCount" : 12, "directInstituteCount" : 0, "authorCount" : 6, "contributorCount" : 0, "hasQualityFactor" : true, "link" : "/api/publication/30566682", "label" : "Cheewawisuttichai Thamrongsak et al.
