A practical and asymmetric synthesis of a small-molecule CXCR7 modulator featuring a highly functionalized and hindered tertiary β-amino amide framework is reported. The cornerstone of this strategy relied on the intermediacy of a reactive aziridinium species, which, following regioselective ring opening with cyanide, furnished the desired chiral β-tertiary amino nitrile for further elaboration.

报道了实用化和不对称合成的小分子CXCR7调节剂,其特征是高度官能化且受阻的叔β-氨基酰胺骨架。该策略的基础是反应性叠氮化合物的中间产物,在用氰化物进行区域选择性开环后,该叠氮化合物提供了所需的手性β-叔氨基腈用于进一步的精制。作为进一步强调该合成策略的一种手段,还介绍了受阻β-氨基酰胺合成的扩大范围。
