phase catalyst-free Biginelli synthesis of novel 5-carbethoxy-4-(3-bromo-4-hydroxy-5-methoxyphenyl)-6-methyl-3,4-dihydropyrimidin-2(1H)-one (C15H17BrN2O5) and 5-carbethoxy-4-(3-bromo-4-hydroxy-5-methoxyphenyl)-6-methyl-3,4-dihydropyrimidin-2(1H)-thione (C15H17BrN2O4S) has been carried out under microwave irradiation at 400W. The structures of both compounds were confirmed by 1H NMR, 13C NMR, Mass, FT-IR
摘要 新型 5-carbethoxy-4-(3-bromo-4-hydroxy-5-methoxyphenyl)-6-methyl-3,4-dihydropyrimidin-2(1H)-one (C15H17BrN2O5) 的固相无催化剂 Biginelli 合成和5-carbethoxy-4-(3-bromo-4-hydroxy-5-methoxyphenyl)-6-methyl-3,4-dihydropyrimidin-2(1H)-thione (C15H17BrN2O4S) 已在 400W 的微波辐射下进行。两种化合物的结构均通过1H NMR、13C NMR、质谱、FT-IR、元素分析和单晶X射线衍射法确证。通过以 0.35 × 0.30 × 0.25 mm 尺寸的 (C15H17BrN2O5) 和 0.35 × 0.32 × 0.30 mm 尺寸的 (C15H17BrN2O4S) 结晶获得两种化合物的单晶。这两种化合物
