Synthetic study of akaterpin: Determination of the relative stereochemistry of the upper decalin moiety with disulfated hydroquinone

In order to establish the stereochemistry of akaterpin, a specific inhibitor of PI-PLC, synthesis of cis-decalin 2 and trans-decalin 3 was carried out. Comparison of NMR spectra of 2 and 3 with that of akaterpin indicated that the upper decalin has a cis-fused structure.
