Novel α-amino squaric acid analogs were synthesized by initial addition reaction of a dianion enolate generated from N-Boc amino acid tert-butyl ester to squaric acid diisopropyl ester, and subsequent decarboxylation of the resulting carboxylic acid moiety.
通过使由N- Boc氨基酸叔丁酯生成的二价阴离子烯酸酯与方酸二异丙酯进行初始加成反应,然后使所得羧酸部分脱羧,来合成新型α-氨基方酸类似物。
