General synthetic methods for the preparation of 4-(2-aminophenyl)-4-hydroxypiperidine derivatives have been developed. The application use of these derivatives in the synthesis of 1'-substituted spiro [4H-3, 1-benzoxazine-4, 4'-piperidin]-2 (1H)-one derivatives is described, and the antihypertensive activity of the products is also reported.
已开发出4-(2-氨基苯基)-4-羟基哌啶衍生物的通用合成方法。文中描述了这些衍生物在合成1'-取代的螺[4H-3, 1-苯并噁嗪-4, 4'-哌啶]-2(1H)-酮衍生物中的应用,并报告了这些产品的抗高血压活性。
