6-dioxaspiro[2.5]octane [available from diethyl (S)-malate] into methyl 2-[(4S)-2,2-dimethyl-5-methylidene-1,3-dioxan-4-yl]acetate, and conditions for diastereoselective reduction of the double C=C bond in the latter have been optimized. The reduction product has been converted into (3S,4S)-3-[tert-butyl(dimethyl)siloxy]-4-methyldecanoic acid which is a building block for the synthesis of arenamides
已经开发了一种有效的方法来转化(7 S)-7-(3-溴丙-1-烯-2-基)-5,5-二甲基-4,6-二氧杂螺[2.5]辛烷[可从二乙基中获得(S)-苹果酸]成2-[((4 S)-2,2-二甲基-5-亚甲基-1,3-二氧六环-4-基]乙酸甲酯]和非对映选择性还原双C = C键的条件在后者中已进行了优化。还原产物已转化为(3 S,4 S)-3- [叔丁基(二甲基)甲硅烷氧基] -4-甲基癸酸,这是合成芳酰胺A和C的基础材料,具有明显的抗肿瘤作用的天然化合物活性并有效抑制二氧化氮和前列腺素E 2(PGE2)。
