[图片]我们已经实现了全合成的阿帕曲霉毒素a,其中噻唑啉的形成是由含有酰胺4的moys使用PPh3(0)/Tf2O完成的。对17中的Troc和烯丙基酯进行脱保护,与三肽3偶联,对烯丙基酯和Fmoc进行脱保护,然后进行大内酰胺化,产生了apapoxin A(1)。
[GRAPHICS]We have achieved a total synthesis of apratoxin A in which thiazoline formation was accomplished from the moCys containing amide 4 using PPh3(0)/Tf2O. Deprotection of the Troc and allyl ester in 17, coupling with tripeptide 3, and deprotection of the allyl ester and the Fmoc, followed by macrolactamization provided apratoxin A (1).
