摘要
以甲氧基取代苯甲醛和氯仿为起始物,以四丁基溴化铵(TBAB)为催化剂,在氢氧化钠溶液中反应制得甲氧基取代扁桃酸钠,经酸化得到相应的甲氧基取代扁桃酸;在三氟化硼-乙醚催化下,甲氧基取代扁桃酸分别与不同的酚类化合物发生串联的酯化-分子内环合反应,便捷、高效地合成了13种3-芳基苯并呋喃酮类化合物.采用噻唑蓝(MTT)法对其中11种化合物进行了肿瘤细胞增殖抑制活性研究,结果表明化合物4b,4j及4a,4i具有较强的抗肿瘤活性.
tarting from methoxyl-substituted benzaldehydes and chloroform,a series of methoxyl-substituted mandelic sodium salts were synthesized in the presence of sodium hydroxide and catalytic amount of tetrabutylammonium bromide( TBAB),the corresponding methoxyl-substituted mandelic acids could readily be obtained by acidification. These intermediates on reaction with various substituted phenols in the presence of boron trifluoride etherate via a sequential esterification-alkylation process to give 13 3-arylbenzofunanone analogues in high yields with simple procedures. The inhibitory effects of 11 compounds on cell proliferation were investigated by methylthiazolyldiphenyl-tetrazolium bromide(MTT) method using SW620,A549 and MNNG/HOS cell lines. The results showed that the 3-arylbenzofunanone analogues 4b,4j and 4a,4i exhibited some activities against the proliferation of the cell lines.
