Abstract
Objective: To synthesize 5-(2-(methoxycarbonyl)-trans-ethenyl)-7-methoxy-2-(4-benzyloxyphenyl)benzo[b]furan through Vilsmier reaction,elimination reaction and substituted reaction.Methods: By studying the relative literatures,we found the way to synthesize 5-(2-(methoxycarbonyl)-trans-ethenyl)-7-methoxy-2-(4-benzyloxyphenyl)benzo[b]furan.Results: 5-(2-(methoxycarbonyl)-trans-ethenyl)-7-methoxy-2-(4-benzyloxyphenyl)benzo[b]furan was synthesized.Conclusion: Its yield was 25.2%,mp170-171 ℃ and purity 99.08%.
