to prepare bistramide C and 39-oxobistramide K, was synthesized in 19 steps with an overall yield of 6.2%. Furthermore, the chemoselective reduction of the ketone at C-39 was performed giving an easy access to bistramides A, B, D, K, and L. Finally, the versatility of the synthesis of the C14–C40 fragment can allow the preparation of a large variety of stereoisomers to produce bistramide analogues.
可以用来制备双链酰胺C和39-氧杂双酰胺K的平台C14-C40,分19个步骤合成,总收率为6.2%。此外,在C-39处对酮进行了化学选择性还原,使得可以轻松获得双链酰胺A,B,D,K和L。最后,C14-C40片段合成的多功能性可以制备C14-C40片段。各种立体异构体可生产双链酰胺类似物。
