The stereospecifictotalsynthesis of the pro-resolving and tissue-regenerative Protectin sulfido-conjugates: 16R,17S-PCTR1, 16R,17S-PCTR2, and 16R,17S-PCTR3, derived from docosahexaenoic acid, has been achieved. The key intermediate 16S,17S-epoxy-Protectin methyl ester was synthesized using the Sharpless catalytic asymmetric epoxidation to generate the chiral centers at C16 and C17. A Cs2CO3 promoted
源自二十二碳六烯酸的促分辨和组织再生性保护素硫苷-共轭物的立体定向全合成:16 R,17 S -PCTR1、16 R,17 S -PCTR2和16 R,17 S -PCTR3。实现。使用Sharpless催化不对称环氧化合成关键中间体16 S,17 S-环氧-Protectin甲酯,以在C16和C17处生成手性中心。Cs 2 CO 3促进的偶联提供了跳过的二炔中间体。谷胱甘肽,l-半胱氨酰甘氨酸和l的Wittig反应和环氧化物开环-半胱氨酸甲酯盐酸盐分别是合成中的关键步骤。
