A new synthetic route to aminomethylpsoralens, substituted on the furan-ring, has been developed by electrophilic substitution of N-hydroxymethylphthalimide and subsequent hydrazinolysis. Hydroxy and methoxy activating functions on the psoralens lead to multi-site substitution and the products of these phthalimido-methylations resist simple cleavage with hydrazine. The two-step introduction of a single
通过亲电取代N-羟甲基邻苯二甲酰亚胺并随后进行肼解反应,已开发出一种新的合成路线,可合成呋喃环上的氨基甲基补骨脂素。补骨脂素上的羟基和甲氧基活化功能导致多位取代,这些邻苯二甲酰亚胺基甲基化产物抵抗肼的简单裂解。在仅包含甲基取代基的补骨脂素中,成功地将CH 2 NH 2基团分为两步引入是成功的。
