A Synthesis of the Chlorosulfolipid Mytilipin A via a Longest Linear Sequence of Seven Steps

Magnificent seven : The chlorosulfolipid mytilipin A was synthesized in racemic form in seven steps and in enantioenriched form in eight steps. Key transformations include a highly diastereoselective bromoallylation of a sensitive α,β‐dichloroaldehyde, a kinetic resolution of a vinyl epoxide, a convergent and highly Z ‐selective alkene cross‐metathesis, and a chemoselective and diastereoselective dichlorination of a complex diene.
