We report short and efficient scalable syntheses of enantiomerically pure (3R,4S)-3-(hydroxymethyl4-(hydroxyethyl))-piperidine and 1-hydroxymethyl-octahydro-1H-pyrano[3,4-c]pyridine scaffolds. The alkaloid core was readily synthesized from naturally occurring quinine and can serve as a valued starting point for drug-discovery.

我们报告对映体纯(3 R,4 S)-3-(羟甲基4- (羟乙基))-哌啶和1-羟甲基-八氢-1 H-吡喃并[3,4- c ]吡啶骨架的短而有效的可扩展合成。生物碱核心很容易由天然存在的奎宁合成,可以作为药物发现的重要起点。末端1,2-二醇的裂解和酸催化的环氧化物开放环化是其中涉及的关键步骤。对于每个支架,合成了预计的小分子文库的许多成员。
