A flexible and highly diastereoselective formal synthesis of hapalosin, a cyclodepsipeptide isolated from the blue green alga Hapalosiphon welwitschii and having multidrug-resistance-reversing activity is described. The synthetic route involves the addition of organometallic reagent to N-tert- butanesulfinylimine, Jung nonaldol aldol reaction, and Yamaguchi esterification as key steps.

The marine natural product hapalosin and 22 analogs, which incorporated systematic substituent deletions or variations, were prepared. These compounds were evaluated in a cell-based assay for both MDR-reversing activity and general cytotoxicity. Some substituent modifications resulted in lower cytotoxicities, but most structural changes were either detrimental to or did not seriously alter the MDR-reversing activity.
