3-dihydrofurocoumarin and furocoumarin-2,3-dihydrofurocoumarin hybrids was performed by two alternative pathways, either involving a catalyzed transformations of the ethynyl derivatives of plant coumarins - peucedanin or peuruthenicin. OBJECTIVE AND METHODS The Sonogashira reaction of 7-ethynyl coumarins or 3-ethynyl-2-isopropylpsoralen with the subsequent coumarin triflates led to 7,7´-linked bicoumarins or 3
背景技术7,7。连接的双香豆素,3,3。连接的双(2-异丙基)补骨脂素以及1H-1,2,3-三唑连接的香豆素-2,3-二氢呋喃香豆素和呋喃香豆素-2,3的合成-二氢呋喃香豆素杂种通过两种替代途径进行,涉及植物香豆素的乙炔基衍生物-Peucedanin或peuruthenicin的催化转化。目的和方法7-乙炔基香豆素或3-乙炔基-2-异丙基补骨脂素与随后的香豆素三氟甲磺酸酯的Sonogashira反应导致7,7′-连接的双香豆素或3,3′-连接的双补骨脂素。1,2,3-三唑连接的香豆素-2,3-二氢呋喃香豆素或呋喃香豆素-2,3-二氢呋喃香豆素杂化物是通过2-氮杂环戊酮与7-炔基香豆素或3-乙炔基-2-异丙基补骨脂素的区域选择性Cu催化的环加成反应合成的。结果合成的双香豆素在体内具有抗凝活性的药理学筛选显示,与1,2,3-三唑环20和22连接的香豆素-二氢呋喃香豆素杂种是活性最高的化合物。所呈递的凝血酶原时间(PT)值与100
