heterocyclic compounds - chromeno[6',7':4,5]furo[3,2-c][1,2]oxazine. The (E)-isomer in this condition was transformed into (E)-3-(hydroxyimino)-2-(propan-2-ylidene) furocoumarin. RESULTS Pharmacological screening of the synthesized 1,2-oxazine-fused linear furocoumarins for anti-inflammatory and analgesic activity in vivo revealed that this compounds possessed high activity which was depend on the substitution
背景技术进行1,2-恶嗪稠合的线性呋喃香豆素的合成,涉及植物香豆素或异黄酮衍生物的过渡金属催化反应。目的与方法钯催化的2-(甲苯磺酰基)oseoselone与末端炔烃的脱硫交叉偶联反应以及所获得的2-(芳基乙炔基)呋喃香豆素的过量羟胺的连续处理给出了预期的(Z,E)-3 -(羟基亚氨基)-2-(芳基乙炔基)呋喃香豆素,其(Z:E)比率为约1:0.5。金(III)催化呋喃香豆素β,γ-炔属(Z)-肟的环异构化反应导致了一组新的杂环化合物-铬诺[6',7':4,5]呋喃[3,2-c] [ 1,2]恶嗪。在这种条件下的(E)-异构体被转化为(E)-3-(羟基亚氨基)-2-(丙烷-2-亚烷基)呋喃香豆素。结果合成1的药理筛选 2-恶嗪融合的线性呋喃香豆素在体内具有抗炎和镇痛作用,表明该化合物具有高活性,这取决于恶嗪单元芳香环中的取代。发现实验研究的结果与计算机对接结果一致。结论化合物的中等毒性(LD50值大于2000
