A synthetic route for highly substituted conjugated ketones has been developed utilizing glycals as starting materials. The two‐step process combined the Heck reaction/Lewis acid promoted ring opening to afford the products in 33–80 % overall yields and with a high level of trans stereoselectivity. The products showed activity against several cancer cell lines, in some instances overperforming cisplatin
已经开发了利用糖基作为起始原料的高度取代的共轭酮的合成途径。两步过程结合了Heck反应/路易斯酸促进的开环,以33-80%的总收率提供了高产率的产品,并具有很高的反式立体选择性。该产品显示出对几种癌细胞系的活性,在某些情况下,其表现优于用作标准的顺铂。
