The invention relates to a process for the preparation of anagrelide, and for the preparation of intermediates for use in preparing anagrelide. The invention also relates to the inteπnediates per se, in particular compounds of formula (V) where R constitutes a suitable leaving group, which may not be hydrogen. The R group may be is selected from: (i) -SiR13, (ii) -CH2Ar, (iii) -COOR2, and (iv) sulfonates such as -SO2R3.
摘要:
The present invention relates to compositions comprising at least omega-3 lipid compounds substituted at the 2-positions having therapeutic activity. More specifically, the present invention relates to a composition comprising at least omega-3 lipid compounds substituted at the 2-position, counted from the functional group (X) of the omega-3 lipid compound, wherein the omega-3 lipid compounds comprise: a compound of general formula (I): and a compound of formula (II): wherein R1 and R2 are the same or different and are chosen from a hydrogen atom, a hydroxy group, an alkyl group, a halogen atom, an alkoxy group, an acyloxy group, an acyl group, an alkenyl group, an alkynyl group, an aryl group, an alkylthio group, an alkoxycarbonyl group, a carboxy group, an alkylsulfinyl group, an alkylsulfonyl group, an amino group, and an alkylamino group; and X represents a carboxylic acid or a derivative thereof, a carboxylate, a carboxylic anhydride, a hydroxymethyl (-CH2OH) or a pro-drug thereof, or a carboxamide, or any pharmaceutically acceptable complex, salt, solvate, or pro-drug, with the provisos that: R1 and R2 are not simultaneously hydrogen.
摘要:
The present invention relates to a process for preparing sulfonyl halides comprising the steps of a) reacting an enoxymetal, allylsilane or allylstannane compound, preferably in the presence of a diene, with sulphur dioxide and b) adding a suitable halogen source to the metal sulfinate intermediate of step a). Furthermore, the present invention relates to new sulfonyl chlorides, bromides, and iodides, sulfonamides and sulfonates. In addition, the present invention teaches the use of the new multifunctional sulfonamides and sulfonates for the preparation of a medicament, bacteriocides, fungicides, pesticides, and herbicides as well as the use of sulfonyl chlorides for the preparation of sulfonamides and sulfonates.
