Aminopropyltriethoxysilane was first reacted with hexamolybdate anions and then treated with glucose to prepare Glu\/Si(OEt)2(CH2)3N = Mo[Mo5O18]. Nano-silica was then modified by the prepared glucose\/molybdate complex to obtain SiO2@Glu\/Si(OEt)2(CH2)3N = Mo[Mo5O18]. The developed catalyst was characterized by FT-IR, EDX, XRD, FE-SEM and TGA analyzes. Its catalytic efficiency was investigated for the preparation of pyrano[2,3-d]pyrimidine derivatives by the reaction between various aldehydes, malononitrile and barbituric acid. The desired products were prepared in the presence of 0.004 g of the prepared catalyst in high to excellent yields.<\/jats:p>","DOI":"10.17344\/acsi.2021.6819","type":"journal-article","created":{"date-parts":[[2025,5,4]],"date-time":"2025-05-04T04:22:27Z","timestamp":1746332547000},"page":"30-38","source":"Crossref","is-referenced-by-count":3,"title":["Glucose-Decorated Silica-Molybdate Complex: A Novel Catalyst for Facile Synthesis of Pyrano[2,3-d]-Pyrimidine Derivatives"],"prefix":"10.17344","volume":"69","author":[{"given":"Arezoo","family":"Pourkazemi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Negin","family":"Asaadi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mahnaz","family":"Farahi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ali","family":"Zarnegaryan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bahador","family":"Karami","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7072","published-online":{"date-parts":[[2022,3,15]]},"container-title":["Acta Chimica Slovenica"],"original-title":[],"deposited":{"date-parts":[[2025,5,4]],"date-time":"2025-05-04T04:22:28Z","timestamp":1746332548000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.matheo.si\/index.php\/ACSi\/article\/view\/6819"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,3,15]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2022,3,15]]}},"URL":"https:\/\/doi.org\/10.17344\/acsi.2021.6819","relation":{},"ISSN":["1580-3155"],"issn-type":[{"value":"1580-3155","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,3,15]]}}}
