 2-pyrrolesulfenic acid + 2-aminoacrylate precursor of the orange-red pigment formed upon wounding. Two molecules of 2-pyrrolesulfenic acid give rise to highly reactive S-(2-pyrrolyl)2-pyrrolethiosulfinate which in turn converts into red 2,2'-epidithio-3,3'-dipyrrole (dipyrrolo[2,3-d:2',3'-e]-1,2-dithiin) ?
