annonaceous acetogenins is described in the synthesis of the 14,21-diepimer (14) of squamocin-K. The synthesis utilized the controlled sequence of ring-closing metathesis (RCM) and cross metathesis (CM) reactions to incorporate the stereocenters and skeleton from (3R,4R)-1,5-hexadiene-3,4-diol and 10-chloro-1-decene. The lactone moiety was attached through nucleophilic substitution and achieved the
在squamocin - K的14,21-二聚体(14)的合成中描述了一种新的制备非乙酰丙酮原的方法。该合成利用了闭环复分解(RCM)和交叉复分解(CM)反应的受控序列,将(3 R,4 R)-1,5-己二烯-3,4-二醇和10-氯-1-癸烯。内酯部分通过亲核取代连接并实现去对称化。还评估了14对人激素难治性前列腺癌细胞系(PC-3)的抑制活性。
