Method for synthesizing kukoamine A and analogue thereof

The invention relates to the technical field of medicines, and relates to a method for synthesizing a natural product kukoamine A and analogue thereof. The method comprises the following steps: (1) performing a nucleophilic reaction on hydroxyl, halogen or C1-C10 alkoxy or C1-C10 alkyl substituted or unsubstituted benzaldehyde and malonic acid to obtain a compound 1; (2) reacting the compound 1 in the step (1) with N-hydroxy succinimide to obtain a compound 2; (3) reacting the compound 2 with spermine to obtain a compound 3; and (4) reacting the compound 3 with hydrogen to reduce carbon-carbon double bond, and purifying. The preparation method is simple, and provides a compound base to pharmacological activity research of compounds with similar structures. 本发明涉及医药技术领域，涉及天然产物地骨皮甲素及其类似物的合成方法。该方法包括：1)由羟基、卤素或C1-C10烷氧基或C1-C10烷基取代或未取代的苯甲醛与丙二酸进行亲核反应得化合物1；2)步骤1)所得化合物1和N-羟基琥珀酰亚胺反应，得化合物2；3)化合物2和精胺反应，得化合物3；4）化合物3用氢气反应以还原碳-碳双键，纯化即得。本发明制备方法简单，为类似结构化合物的药物活性研究提供了化合物基础。
