A strained 14-memberedcyclopeptide was prepared from the Garner aldehyde derived from D-serine. The key steps in the synthesis were the construction of the alkyl-aryl ether linkage via an SNAr reaction involving 4-fluorobenzonitrile and the macrolactamization using a modification of the Schmidt protocol involving an activated pentafluorophenyl ester.
由衍生自D-丝氨酸的加纳醛制备了应变的14元环肽。合成中的关键步骤是通过涉及4-氟苄腈的S N Ar反应构建烷基-芳基醚键,并使用涉及激活的五氟苯基酯的Schmidt方案的改进进行大内酰胺化。
