Synthesis of 5-(2-(methoxycarbonyl)-trans-ethenyl)-7-methoxy -2-(4-benzyloxyphenyl)benzo[b]furan

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 0C and purity 99.08%.
