Artifficial Urushi:Design,Synthesis,and Enzymatic Curing of New Urushiol Analogues

"Artificial urushi"was prepared by laccase-catalyzed curing of new urushiol analogues.The curing of the catechol derivative having a linolenoyl group proceeded in the presence of acetone powder,yielding the crosslinked film (artificial urushi)with high hardness and gloss surface,which are comparable with those of natural urushi coating.
