report the preparation of a hydroisoquinoline intermediate potentially useful for the synthesis of some excitatory amino acid antagonists. The requisite stereochemistry is established by an intramolecular Diels-Alder reaction, and the absolute stereochemistry is ultimately derived from S-aspartic acid. Also reported is an efficient synthesis of methyl N-CBZ aspartate β-aldehyde.
