Total synthesis of viridiofungin A

Viridiofungin A, a member of amino alkyl citrate antibiotics from Trichoderma viride, was enantioselectively synthesized in naturally occurring form for the first time, employing regio- and stereoselective opening of the chiral glycidate with vinylmagnesium bromide and alkene cross metathesis of the citric acid core and hexadec-15-en-8-one as key steps.
