  • [EN] PROCESS FOR THE PREPARATION OF A POLYUNSATURATED KETONE COMPOUND<br/>[FR] PROCÉDÉ POUR LA PRÉPARATION D'UN COMPOSÉ POLYINSATURÉ DE CÉTONE
    申请人:AVEXXIN AS

    The invention relates to the manufacture of certain polyunsaturated compounds employing a particular application of the Mitsonobu reaction in the presence of at least one anti-oxidant. We have found a method of making a pharmaceutically-acccptable polyunsaturated ester or thioester compound directly, which can ultimately be converted to the advantageous ketone compounds, in which unwanted oxidation and cis/trans isomerization are substantially reduced or eliminated using particular Mitsonobu chemistry.
    这项发明涉及在至少一种抗氧化剂存在的情况下,利用Mitsonobu反应的特定应用制造某些多不饱和化合物。我们发现了一种直接制造药用可接受的多不饱和酯或硫酯化合物的方法,最终可以转化为有利的酮化合物,其中使用特定的Mitsonobu化学方法大大减少或消除了不需要的氧化和題/反式异构化。

    A process for the preparation of a polyunsaturated thiol comprising: (1) reacting a polyunsaturated alcohol in the presence of a compound of formula R2-SO2Hal wherein R2 is a C1-20 hydrocarbyl group, such an C1-10 alkyl group, to form a polyunsaturated sulphonyl ester; (2) converting the polyunsaturated sulphonyl ester to a polyunsaturated thioester by reacting with an anion of formula -SC(=O)R4 wherein R4 is a C1-20 hydrocarbyl group; (3) converting the polyunsaturated thioester to form a polyunsaturated thiol optionally in the presence of an antioxidant, e.g. using a metal carbonate. (4) reacting said polyunsaturated thiol with a compound (LG)R3COX wherein X is an electron withdrawing group and R3 is an alkylene group carrying a leaving group (LG), such as LG-CH2- forming (I) where X is an electron withdrawing group and LG is a leaving group; optionally in the presence of an antioxidant, so as to form a polyunsaturated ketone compound.

    The synthesis of the marine natural product 1,6Z,9Z,12Z,15Z-octadecapentaen-3-one (1) has been achieved by two different routes starting from the ethyl esters of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), respectively. Using EPA ethyl ester as starting material the polyunsaturated vinyl ketone lipid 1 was obtained in 17% overall yield.
