AbstractA simple and efficient one‐pot oxidation synthesis of N‐1‐piperidonyl amides was successfully developed through the double oxidation of hydrazides (involving hydrazonium formation, azodioxy‐carbonyl compounds generation, and α‐carbon oxidation) by using meta‐chloroperbenzoic acid (mCPBA). The convenient oxidation method was also extended to Rimonabant analogue. The lactam oxidized Rimonabant analogue was first successfully synthesized for demonstrating the construction and characterized by NMR spectroscopic methods and the single‐crystal X‐ray diffraction study (ORTEP).
摘要 利用间氯过苯二甲酸(mCPBA)对酰肼进行双重氧化(包括酰肼形成、偶氮二氧羰基化合物生成和α-碳氧化),成功地开发了一种简单高效的N-1-哌啶基酰胺的一锅氧化合成方法。这种简便的氧化方法也扩展到了利莫那班类似物上。首先成功合成了内酰胺氧化的利莫那班类似物,并通过核磁共振光谱方法和单晶 X 射线衍射研究(ORTEP)对其进行了表征。
