5-(2,2-Dimethyl-4<i>H-</i>1,3-benzodioxin)methanol: the synthetic precursor to <i>o</i>-formyl-<i>m</i>-hydroxycinnamic acid, the most oxidized salicylaldehyde-type phytotoxin isolated from rice blast fungus, <i>Magnaporthe grisea</i>
Abstract o-Formyl-m-hydroxycinnamic acid, the most oxidized salicylaldehyde-typephytotoxin isolated from riceblastfungus, Magnaporthegrisea, was synthesized for the first time using 5-(2,2-dimethyl-4H-1,3-benzodioxin)methanol as the starting material, and the proposed structure was confirmed.
