Enantioselective total synthesis of β-zearalenol from (s)-propylene oxide

The total synthesis of 14-membered resorcylic acid macrolide, β-zearalenol, was accomplished starting from commercially available enantiomerically pure propylene oxide and methyl 2,4-dihydroxy-6-methylbenzoate using Grignard reaction, asymmetric dihydroxylation, Yamaguchi macrolactonization, and ring-closing metathesis as key steps.
