The invention relates to a composition comprising A) microcapsules comprising at least one fat-soluble active substance selected from a vitamin K compound or a provitamin or a prodrug of a vitamin K compound embedded in a matrix comprising a hydrocolloid and optionally one or more other matrix components, and B) at least one dietary mineral; as well as uses and products comprising such compositions.

Formulation of fat-soluble vitamin

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.

Prodrugs of vitamin K

The invention 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.

Prodrugs of vitamine K

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) is defined including a step in which (i) a compound of formula (II) is reacted formula (III) wherein R is an alkyl group; LG is a leaving group; m is an integer from 0 to 8; n is an integer from 0 to 9; and X is hydrogen, halide, hydroxyl or protected hydroxyl; in the presence of a copper, nickel or palladium catalyst.
