以异丁香酚为原料, 经氧化银催化的自由基仿生氧化偶联反应, 一步合成了天然苯并二氢呋喃新木脂素licarin A (1), 然后经2,3-二氯-5,6-二氰基对苯醌(DDQ)氧化脱氢反应得到另一苯并二氢呋喃新木脂素化合物2-(3'-甲氧基-4'-羟基)苯基-3-甲基-5-甲酰乙烯基-7-甲氧基-2,3-苯并二氢呋喃(2). 以苯并二氢呋喃新木脂素12为底物, 以甲醇为溶剂, 分别与甲醛、二级胺在酸性介质中发生微波协助的Mannich反应, 合成了11个新的苯并二氢呋喃新木脂素Mannich碱衍生物313. 所合成的化合物通过1HNMR、13CNMR和MS等进行了结构确证, 并采用CCK-8法测试了所合成化合物对人宫颈癌Hela细胞株的体外抑制活性. 结果表明大部分化合物对Hela细胞增殖具有良好的抑制作用, 其中化合物2 (IC50 0.438 μmol/L)和化合物9 (IC50 8.358 μmol/L)具有最强的Hela细胞增殖抑制活性.

The natural benzodihydrofuran neolignans licarin A (1) was synthesized from isoeugenol through biomimetic oxidative coupling. Then licarin A (1) was transformed into another benzodihydrofuran compound 2-(3'-methoxy-4'-hydroxy)- phenyl-3-methyl-5-formylvinyl-7-methoxy-2,3-benzodihydrofuran (2) through 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) oxidative reaction. Based on Mannich reaction of 1 or 2 with viarious secondary amines and formaldehyde in acidic alcohol system under microwave-assistanced, eleven new benzodihydrofuran neolignan Mannich base derivatives 313 were synthesized. All the synthetic compounds were tested for antiproliferation activity against human cervical carcinoma Hela cells by the standard CCK-8 method. The results showed that most of the target compounds exhibited moderate to potent antiproliferation activity against Heala cells. Among them, compound 2 (IC50 0.438 μmol/L) and compound 9 (IC50 8.358 μmol/L) displayed the strongest antiproliferation activity against Hela cells.
