An efficient and simple procedure for the syntheses of 4-aryl-1,2,3,4-tetrahydroisoquinolines and 1-aryl-2,3,4,5-tetrahydro-3-benzoazepines has been developed. The approach uses easily available starting materials and requires just three steps. The hydroamination of an enol carbamate is the key step. This general and direct method has been applied to the total synthesis of the natural alkaloid cherylline
已经开发了一种有效而简单的合成4-芳基-1,2,3,4-四氢异喹啉和1-芳基-2,3,4,5-四氢-3-苯并a庚因的方法。该方法使用容易获得的起始材料,仅需三个步骤。烯醇氨基甲酸酯的加氢胺化是关键步骤。这种通用和直接的方法已经应用于天然生物碱cherylline的全合成以及具有生物活性的3-苯并a庚因。
