An efficient and simple new stereocontrolled access route to novel disubstituted cispentacin derivatives with multiple stereogenic centers from norbornene β‐lactam has been developed. The synthesis involves olefinic bond functionalization by dihydroxylation followed by oxidative ring cleavage and transformation of the dialdehyde intermediate through a Wittig reaction.
已经开发了一种有效且简单的新立体控制的途径,可从降冰片烯β-内酰胺向具有多个立体生成中心的新型双取代顺式戊二酸衍生物进行开发。合成涉及通过二羟基化的烯烃键官能化,然后氧化环裂解和通过维蒂希反应的二醛中间体的转化。
