developed a powerful concept for the rapid assembly of a series of twenty-four homochiral building blocks from simple racemic trans-2,4-dimethyl-8-oxabicyclo[3.2.1]oct-6-en-3-one. The series comprises eight stereochemical pentades of anomeric [3.3.1]lactone acetals, eight stereochemical tetrades of anomeric carbohydrate mimics, and eight stereotetrades of acyclic polypropionate units. The utility of these enantiopure
我们已经开发出了一个强大的概念,可以从简单的外消旋的trans-2,4-二甲基-8-氧杂双环[3.2.1] oct-6-en-3-one快速组装一系列二十四个同手性结构单元。该系列包括八个异头[3.3.1]内酯缩醛的立体化学五单元,八个异头碳水化合物模拟物的立体化学四分体和八个无环聚丙烯酸酯单元的立体四分体。这些对映纯物质(平均94%ee)在天然产物合成中的实用性得到了证明,并显示出可以补充流行的羟醛方法。
