An asymmetric Diels-Alderreaction in the presence of 3.0 M lithiumperchlorate-diethylether was used to generate the initial stereochemistry for a cyclohexane amino acid (3), a key intermediate in the preparation of a fused ring didemnin analog. This constrained ring macrocycle should provide insight into the binding site conformation of the bioactive species.
