Short and efficient formal syntheses of (2R,3R)- and (2R,3S)-3-hydroxypipecolic acids, and total syntheses of (–)-deoxoprosopinine and (+)-2-epi-deoxoprosopinine have been achieved starting from D-glycals. The key steps involved in these syntheses were Ferrier rearrangement, azide reduction, intramolecular cyclization, and Grignard reaction.
(2R,3R)- 和 (2R,3S)-3-羟基哌啶酸的短而有效的正式合成,以及 (-)-deoxoprosopinine 和 (+)-2-epi-deoxoprosopinine 的全合成已经从 D-开始实现糖类。这些合成涉及的关键步骤是费里尔重排、叠氮化物还原、分子内环化和格氏反应。
