摘要

Synthetic investigations of (1, 3′)-bistetrahydroisoquinolines are reported as the key intermediates for the synthesis of ecteinascidin and phthalascidin pentacyclic structure analogues through successive Pictet–Spengler cyclization and intramolecular peptide coupling. The direct Pictet–Spengler reaction between a derivative of l-DOPA and N- protected-α-aminoaldehyde was first extended to the synthesis of cis-(1, 3′)- ...
