title: Synthetic route to the GE3 cyclodepsipeptide.
abstract: [reaction: see text] A reasonably efficient [2 + 2 + 2] fragment condensation strategy has been developed for assembling the cyclodepsipeptide sector of GE3 that involves 5-7. A Carpino HATU-mediated macrolactamization was used to close the 19-membered cyclodepsipeptide ring.
