Synthesis of the C1-C27 portion of the aplyronines

This manuscript describes the use of the anti,anti-diastereoselective aldol reaction of an efficiently generated dipropionate equivalent to construct the C5-C14-portion of the aplyronines. This portion was then coupled with a compound corresponding to C15-C20 of the targets. Further elaboration and an additional coupling led to an intermediate containing C1-C27 with appropriate stereochemistry and functionalization for eventual conversion into the aplyronines.
