prepared by the reaction of xanthene with N-bromosuccinimide. Hydrolysis of 1 with 5% NaOH yields 3-[(9H-xanthen-9-yl)aminocarbonyl]propionic acid (3a). The corresponding methyl ester 3c is obtained from 3a by the action of diazomethane. The butanol derivative 4a can be obtained by reduction of 3a or 3c with LiAlH4. Treatment of 1 with LiAlH4 yields the pyrrolidine derivative 5. N-(9H-Xanthen-9-yl)phthalimide
ñ - (9 ħ -呫吨-9-基)琥珀酰亚胺(1)由呫吨与反应制备Ñ溴代琥珀酰亚胺。水解1用5%NaOH得到3 - [(9 ħ呫吨-9-基)氨基羰基]丙酸(3A)。相应的甲酯3c在重氮甲烷的作用下从3a获得。丁醇衍生物4a可以通过用LiAlH 4还原3a或3c而获得。用LiAlH 4处理1得到吡咯烷衍生物5。ñ-(9 H -Xanthen-9-yl)邻苯二甲酰亚胺(2)经历类似的反应,如其类似物1。
