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.
