In our pursuit of an efficient, protecting-group-free synthesis of the dual CCK1/CCK2 receptor antagonist 1, we have developed chemoselective conditions for sulfonamide formation reaction in pure water and a PhNMe2 mediated carboxamide formation, both in the presence of a carboxylic acid. Practical synthesis of an unnatural, chiral β-aryl-α-amino acid is also described.
在我们追求高效且无需保护基团的CCK1/CCK2受体拮抗剂1的合成过程中,我们已经开发出在纯水中进行磺酰胺形成的化学选择性条件,以及在苯胺甲基化物介导下、存在羧酸的情况下进行羧酰胺形成的反应。此外,还描述了非天然手性β-芳基-α-氨基酸的实际合成方法。
