A Concise Enantioselective Synthesis of the Chlorosulfolipid Malhamensilipin A

The first enantioselective synthesis of a member of the chlorosulfolipid family of natural products is reported. All of the polar substituents of malhamensilipin A are introduced with high stereoselectivity, and the unique (E)-chlorovinyl sulfate is created by a chemo-, regio-, and stereoselective E2 elimination of HCl in a reaction that likely has a counterpart in the biosynthesis of this fascinating natural product.
