Synthesis of new 1, 8-dioxo-octahydroxanthene derivatives containing 4-thiazolidinone moiety containing 4-thiazolidinone moiety

A series of novel 1, 8-dioxo-octahydroxanthene derivatives containing 4-thiazolidinone framework (4a-f) were synthesized through a four-step reaction starting from the reduction of nitro derivatives of 1, 8-dioxo-octahydroxanthenes. The resulting aminoxanthenes converted to thiourea derivatives via their reaction with methyl isothiocyanate. The final products were synthesized through the re...

Methyl 2 , 5 - Dihydroxy - 4 - ( 3 1 - methyl - 2 1 - butenyl ) benzoate

Methyl 2,5-dihydroxy-4-(31-methyl-21-butenyl)benzoate (1) was isolated from the root of Erythrina subumbrans. The chemical structure of 1 has been elucidated based on spectroscopy UV-Vis, HRESIMS, 1D and 2D NMR analysis.
