Syntheses of α-amino squaric acids using an aminomalonate equivalent bearing a squaryl group

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 deprote
