α-Acylamino-α,α-disubstituted ketones are of interest as ecdysone agonists. Solid phase synthesis of prototypical α-acylamino-α,α-disubstituted ketones on two different solid supports is described. In both cases the ketone was formed by reaction of a Grignard reagent with an N-acyl-α,α-disubstituted amino acid immobilized through its carboxylate as a Weinreb amide derivative.
α-酰基氨基-α,α-二取代的酮作为蜕皮激素激动剂是令人感兴趣的。描述了在两种不同的固体载体上的原型α-酰基氨基-α,α-二取代酮的固相合成。在这两种情况下,酮都是通过格氏试剂与通过其羧酸盐固定为Weinreb酰胺衍生物的N-酰基-α,α-二取代氨基酸反应形成的。
