A stereospecific synthesis of (+)-muscarine iodide (1) has been achieved starting from D-glucose as a chiral precursor. The key steps of the synthesis involved a stereospecific cyclization of 3,5-di-O-mesyl derivative 3 into the 2,5-anhydride 4, the stereospecific catalytic hydrogenation of unsaturated derivative 6, and the C-4 epimerization of alcohol 12 by Mitsunobu reaction.
一种立体选择性合成(+)肌碱碘化物(1)已经从D-葡萄糖作为手性前体开始实现。合成的关键步骤包括3,5-二-O-甲磺基衍生物3的立体选择性环化成2,5-酸酐4,不饱和衍生物6的立体选择性催化氢化,以及醇12的C-4对映异构化通过三木部反应。
