  The present invention relates to a solid precursor in the form of an organic salt, the solid precursor having a solid support, a method for manufacturing same, and an application thereof. The solid precursor of the present invention enables omission of the [ 18 F]fluoride refining process using additional cartridge, and the use of excessive phase-transfer catalyst, and can easily remove remaining substance after reaction through the solid support inside the precursor. The solid precursor of the present invention is very appropriate for an automated synthesis device as an all-in-one system that can carry out overall process of [ 18 F]fluorosis reaction, when used by charging in a cartridge.

  preparation of diglycerol tetraethers was either performed by condensing suitable blocked monoglycerol diethers by Grubbs metathesis or by reaction of the transmembrane C32-chain with blocked glycerols followed by further alkylation steps. Finally, we could show that the resulting lipids can form closed lipid vesicles comparable to the optically pure counterparts. Therefore, these much simpler lipids compared

  合成了三种具有一条跨膜链的新型二甘油四醚脂质。这些脂质在疏水链的选定位置仅包含两个或四个外消旋甲基分支，这与来自具有类异戊二烯取代模式的古细菌膜的天然脂质相反。甲基部分的插入是从任一（RS）-香茅基溴化物或廉价的甲基丙二酸乙酯。对于链延长，使用Cu催化的格氏试剂偶联反应。甘油二醚的制备通过通过Grubbs复分解缩合合适的封闭单甘油二醚或通过跨膜C32链与封闭甘油的反应进行，然后进行进一步的烷基化步骤来进行。最后，我们可以证明所得的脂质可以形成与光学纯的脂质相当的闭合脂质囊泡。因此，与来自古细菌膜的天然脂质相比，这些简单得多的脂质也适用于制备稳定的定制脂质体。

• 2-Methylalkanoic acids resolved by esterification catalysed by lipase from Candida rugosa: Alcohol chain length and enantioselectivity

  Enantiomerically pure (R)-2-methyldecanoic acid and (S)-2-methyl-1-decanol were prepared in a multi gram scale by esterification reactions catalysed by lipase from Candida rugosa. The enantiomeric ratios (E-values) were determined as a function of the chain length of the alcohol used as the complementary substrate in cyclohexane. In the resolution of 2-methyldecanoic acid the highest value (E = 37 +/- 5) was obtained, when either 1-hexanol, 1-heptanol or 1-octanol were used. In contrast, when resolving 2-methyloctanoic acid, the E-values increased continually with increasing chain length of the alcohol used. 1-Hexadecanol gave the highest value: E > 100. The E-values were determined from the enantiomeric excess (ee) of the product, at, a conversion below 0.4. After two consecutive esterification reactions enantiomerically pure (R)-2-methyldecanoic acid, > 99.8% ee, and after subsequent reduction of the ester produced, (S)-2-methyl-1-decanol, 96.7% ee, were obtained.
