converted to the azide derivative via Mitsunobu reaction with diphenylphosphoryl azide; Pd-C catalyzed hydrogenation of the azide to the amine hydrochloride and then deprotonation of the amine hydrochloride with NaOH furnished the ladostigil and rasagiline analogue 1-aminoindane. These amines and BnOH were reacted with CSI to produce sulfamoyl carbamates, which were converted to sulfamides via Pd-C-catalyzed
摘要 以 5,6,7-三甲氧基茚满-1-酮为原料合成了多巴胺、罗替戈汀、拉多斯替吉尔和雷沙吉兰类似物 2-氨基-4,5,6-三甲氧基茚满和 1-氨基-5,6,7-三甲氧基茚满。第一次以 34% 和 45% 的总收益率。茚满酮的α-羧化、用Et3SiH 还原酮基、酯的碱性水解、酸的Curtius 反应以及加入BnOH 得到相应的氨基甲酸酯。Pd-C 催化的氨基甲酸酯氢解和胺盐酸盐与 NaOH 的去质子化得到多巴胺和 rotigotin 类似物 2-氨基茚满。用 NaBH4 还原 5,6,7-三甲氧基茚满-1-酮得到醇,然后通过与二苯基磷酰基叠氮化物的光信反应将其转化为叠氮化物衍生物;Pd-C 催化叠氮化物氢化成胺盐酸盐,然后用 NaOH 使胺盐酸盐去质子化,得到拉多斯蒂吉尔和雷沙吉兰类似物 1-氨基茚满。这些胺和 BnOH 与 CSI 反应生成氨磺酰氨基甲酸酯,通过 Pd-C 催化的氢解反应将其转化为磺酰胺,总产率为
