Graphical Abstract

Spongidepsin is a macrolide isolated from Spongia sp. Owing to its original structure, exhibiting a phenylalanine amino acid moiety in a macrocycle and the presence of a terminal alkyne, associated to its antiproliferative activity, the molecule has attracted synthetic chemists culminating in seven total and/or formal syntheses. The major differences in the syntheses rely on the methods used to synthesize the C1–C5, the C6–C11, or C6–13 fragments as their connectivities to access spongidepsin are similar. The different methods to synthesize spongidepsin are compared.

Abstract

Seven syntheses of (–)-spongidepsin, a natural product isolated from Spongia sp. with moderate antiproliferative activity, are described and the different analogs obtained during these syntheses are reported. A comparison between the different syntheses has been achieved.
