Objective To design and synthesize a new potential angiogenesis inhibitor
demethyl bryoanthrathiophene. Methods Target molecule-demethyl bryoanthrathiophene was synthesized in 5 steps using 1
8-dihydroxy-9
10-anthraquinone as the starting material
5
7-dihydroxy-1-carboxyl-6-oxo-6H-anthra [1
9-bc] thiophene as the key intermediate and decarboxylization as the key step. Results The target molecule was synthesized with a total yield of 10.1% and identified by MS
IR
UV
1H-NMR
13C-NMR and 2D-NMR. Conclusion Our synthesis of demethyl bryoanthrathiophene is based on an easily-acquired starting material and accomplished with a simple synthetic route.
