Methyl 3,4-dicarboxy-3-hydroxy-19-oxoeicosanoate

Methyl 3,4-dicarboxy-3-hydroxy-19-oxoeicosanoate (3,4-Dicarboxy-3-hydroxy-19-oxoeicosansauremethylester)... 

A homologous aliphatic acid, methyl 3,4-dicarboxy-3-hydroxy-19-oxoeicosanoate (43), has been isolated from Usnea meridensis 210). The structure of this compound followed from the spectroscopic and chemical properties, by comparison with the properties of caperatic acid (41) and by sodium bismuthate oxidation to methyl 3,19-dioxoeicosanoate (44) 210). Caperatic acid (41) and methyl 3,4-dicarboxy-3-hydroxy-19-oxoeico-sanoate (43) have similar optical rotations but the absolute configuration of these acids remains to be determined.
