2-oxothiatole compounds having activity as cPLAinhibitors for the treatment of inflammatory disorders and hyperproliferative disorders

Using a combination of Kumada, Suzuki and Biellmann chemistry, various menaquinones can synthesized rapidly and with stereochemical integrity offering a new way of preparing these vitamin K2 components for the pharmaceutical market. In one embodiment a process for the preparation of a compound of formula (I)  

Process for the preparation of vitamin K2

The disclosure relates to prodrugs of vitamin K2, in particular prodrugs of MK-7 in which the diketone is converted to a monosubstituted or disubstituted ester type derivative. These compounds are shown to give MK-7 in plasma. The disclosure also relates to methods of treating conditions using prodrugs of vitamin K2.
