✦ Synopsis


An enantioselective and convergent synthesis of the C7-C24 fragment of Macrolactin F was achieved from four main fragments. A hydrotelluration/transmetalation sequence was used to install the E,Z diene present in the molecule, while a hydrozirconation/transmetalation sequence was used to connect two advanced intermediates.

Symbiodinolide is a polyol macrolide isolated from the marine dinoflagellate Symbiodinium sp. in 2007. The C14-C24 fragment of symbiodinolide possessing the 17R/18R/21R absolute configuration, which was obtained as one of the degraded products of symbiodinolide, was synthesized stereoselectively fro
