Cardiolipin (CL) is a phospholipid located in both the eukaryotic mitochondrial inner membrane and the bacterial cell membrane. Some bacterial CLs are known to contain cyclopropane moieties in their acyl chains. Although the CLs are thought to be involved in the innate immune response, there have been few attempts at chemical synthesis of the CLs, and detailed studies of their biological activities are scarce. Thus, we have developed a synthetic route to CLs containing chiral cyclopropane moieties.

Starting from a known linear route and a proposed convergent route, we have successfully developed a new hybrid convergent route to MIV-150 that takes advantage of the robust chemistry for the preparation of a fluoroketal and the stereospecific Negishi coupling of an iodocyclopropane moiety to a benzene ring. Stereoselective β- and cis-iodination chemistry was developed for the preparation of an enantiomerically pure iodocyclopropanecarboxylate. Following the Negishi coupling, proven chemistry from the linear route was incorporated, thus ensuring a similar high-purity profile for the final active pharmaceutical ingredient (API). In addition, we have prepared and evaluated a series of basic inorganic and organic MIV-150 salts that have drastically increased water solubility over the parent compound.

A Ni-Al bimetallic catalyzed enantioselective cycloaddition reaction of cyclopropyl carboxamides with alkynes has been developed. A series of cyclopentenyl carboxamides were obtained in up to 99% yield and 94% ee. The bifunctional-ligand-enabled bimetallic catalysis proved to be an efficient strategy for the C-C bond cleavage of unreactive cyclopropanes.

The invention relates to a process for the preparation of cyclopropyl benzyl ketone compounds of formula (II) wherein R1 represents fluorine or chlorine atom or C1-4 alkoxy group, by the reaction of a Grignard reagent, obtained from the reaction of compound of formula (V), wherein X represents chlorine or fluorine atom, with the compound of formula (IV), wherein R2 represents C1-4 alkyl group, having a straight or branched chain. The process can be applied preferably on industrial scale. Compound of formula (II), wherein R represents a fluorine atom in position 2 is an intermediate of the preparation process of prasugrel, which is a platelet inhibitor used in the therapy.
