A highly convergent asymmetric synthesis of the proteinphosphataseinhibitormotuporin 1a is described. Synthesis and coupling of the individual peptide fragments [34 + 35 --> 51] followed by macrocyclization afforded the fully protected motuporin precursor 33, which is converted to the natural product by dehydration and ester hydrolysis. Six of the eight stereogenic centers associated with the natural
