Inspection of the 182 known natural products containing 2,3-epoxy-2-methylbutanoate ester residues revealed a very high tendency in nature for the preferential epoxidation of (Z)-2-methyl-2-butenoate esters (angelates) over (E)-2-methyl-2-butenoate esters (tiglates), since 177 compounds contain epox
