D1/Protectin D1, a potent anti-inflammatory, proresolving, and neuroprotective lipid mediator derived biosynthetically from docosahexaenoic acid, was prepared in an enantiomerically pure form via total organic synthesis. The synthetic strategy is highly stereocontrolled and convergent, featuring epoxide opening of glycidol starting materials for the introduction of the 10(R) and 17(S) hydroxyl groups. The
Neuroprotectin D1/Protectin D1 是一种从二十二碳六烯酸生物合成衍生的强效抗炎、促分解和神经保护脂质介质,通过全有机合成以对映体纯形式制备。合成策略是高度立体控制和收敛的,以缩水甘油起始材料的环氧化物开环为特征,以引入 10( R ) 和 17( S ) 羟基。通过炔前体的顺式还原来确保所需的烯烃Z几何结构,而在末端引入共轭E、E、Z三烯,以最小化Z / E异构化。相同的策略也用于具有 17( R )-立体化学的阿司匹林触发的神经保护素 D1/保护素 D1 的全合成。用所报告的方法获得的合成化合物与内源性材料相匹配,并有助于建立完整的立体化学。
