The synthesis of an amino acid analogue bearing a squaryl group as a carboxylic acid surrogate (sq-AA; 2) has been developed. Aminomalonate equivalent 6 was used as a nucleophilic synthon whose alkylation or conjugate addition reaction followed by deprotection and decarboxylation reaction gave sq-AAs.
已经开发了带有方酸基团的氨基酸类似物作为羧酸替代物 (sq-AA; 2) 的合成。氨基丙二酸等价物 6 用作亲核合成子,其烷基化或共轭加成反应,然后进行脱保护和脱羧反应,得到 sq-AAs。
