Abstract A convenient and practical synthesis of 1,8-dioxo-decahydroacridine derivatives using various aldehydes, 5,5-dimethyl-1,3-cyclohexanedione and thiourea in water, was successfully carried out in the presence of melamine-formaldehyde resin supported H+ (MFRH) as a catalyst. Under solvent-free conditions, rapid and efficient synthesis of 1,8-dioxo-decahydroacridine and N-substituted 1,8-dioxo-decahydroacridine
摘要 在三聚氰胺-甲醛树脂负载的 H+ 存在下,使用各种醛、5,5-二甲基-1,3-环己二酮和硫脲在水中方便实用地合成了 1,8-二氧十氢吖啶衍生物( MFRH) 作为催化剂。在无溶剂条件下,以醋酸铵和芳香胺为氮源,也可以快速高效地合成1,8-二氧十氢吖啶和N-取代的1,8-二氧十氢吖啶衍生物。
