crosslinking amino acid of elastin and is an attractive biomarker for the diagnosis of chronic obstructive pulmonary disease (COPD). Herein, we report an application of the Chichibabin pyridine synthesis to the total synthesis of isodesmosine. Specifically, the appropriate protected lysine and the corresponding aldehyde were reacted using Pr(OTf)3 in H2O/MeOH.
1,2,3,5-四取代的吡啶鎓氨基酸异十二烷酸是弹性蛋白的交联氨基酸,是诊断慢性阻塞性肺疾病(COPD)的有吸引力的生物标记。在本文中,我们报道了Chichibabin吡啶合成在异十二烷总合成中的应用。具体地,使用Pr(OTf)3在H 2 O / MeOH中使适当的被保护的赖氨酸和相应的醛反应。
