A divergent synthesis of two new muscarine analogues bearing the (5S)-dioxolanyl isosteric group was achieved starting from d-glucose, enabling access to libraries of potential muscarinic agonists or antagonists. The key step of the synthesis involved a regioselective epoxide ring opening in 2,5:3,4-dianhydro derivatives 5 and 15 with LiAlH4, whereby the natural stereochemistry of (+)-muscarine (1)
从d-葡萄糖开始,实现了两个新的带有(5 S)-二氧戊环基等规基团的新毒蕈碱类似物的合成,从而可以访问潜在的毒蕈碱激动剂或拮抗剂库。合成的关键步骤涉及在具有LiAlH 4的2,5:3,4-二脱水衍生物5和15中的区域选择性环氧化物开环,从而使(+)-毒蕈碱(1)和(-)-同素异形-有效地建立了毒蕈碱(2)。
