| titleOfInvention | Process for preparation of MK-7 type of vitamin K2 |
| abstract | As a method for the preparation of the MK-7 type of vitamin K 2 , according to the "1+6" synthesis strategy, hexaprenyl chains in the "all-trans" orientation are transferred to the monoprenyl derivatives of menadiol. It is characterized by connecting. According to the present invention, R 1 is an α-sulfonyl carbanion produced in situ from a protected monoprenyl menadiol of formula (II) representing a C 1-3 -alkyl group, X is a halogen Hexaprenyl halide of formula (VII) representing an atom, preferably bromine, and in which both Z'and Z" are H, or one of Z'and Z" represents H and the other is a phenylsulfonyl group -SO 2 Ph group And reacted in an alkylation reaction. The hexaprenyl halide of formula (VII) is obtained by coupling two triprenyl units with or without separation of an intermediate in an alkylation reaction. |
