✦ Synopsis
A convergent synthesis of the C31-C46 domain of the phorboxazole natural products has been developed. This involved the preparation of a C39-C46 dienyl iodide and a C31-C37 aldehyde, followed by their Cl('12-mediatcd coupling and final installation of the C46 (E)-vinyl bromide via an alkyne hydrostannation-bromination sequence.
