The renewable macrocyclic musk 3-methylcyclohexadec-6-enone was prepared via macrocyclic olefin metathesis on gram scale using two different protocols: a room temperature batch process which afforded a 57% yield of the desired macrocycle, but required long reaction times (5 d). In contrast, a continuous flow strategy provided a lower yield of 32% of macrocycle, although the short reaction times (150
可再生的大环麝香3-甲基环十六烷基-6-烯酮是通过使用两种不同的方法以克级通过大环烯烃复分解制得的:室温间歇法,该方法提供了所需大环化合物的57%的收率,但需要较长的反应时间(5天) 。相反,尽管短的反应时间(150°C,5分钟)提高了通量(1 g / 4.8 h),但是连续流策略提供了32%的大环化合物较低的收率。还对涉及带有三取代烯烃的底物的其他大环化进行了间歇和连续流动方案的测试。
