A synthesis of (L, L)-N,N-dimethylcycloisodityrosine 4 based on intramolecular SNAr reaction is reported. A possible explanation was proposed to account for the facile epimerization encountered in the cycloetherification of dipeptide (L,L)-10 and a solution to this problem led to a formal total synthesis of deoxybouvardin.
-的合成(L,L)Ñ,Ñ -dimethylcycloisodityrosine 4基于分子内小号Ñ报道的Ar反应。提出了一种可能的解释,以解释在二肽(L,L)-10的环醚化中遇到的容易的差向异构化,解决该问题的方法导致了脱氧布瓦丁的正式全合成。
