title: Absolute configuration and tautomeric structure of xylindein, a blue-green pigment of Chlorociboria species.
abstract: The S absolute configuration of both chiral centers of xylindein was assigned using X-ray crystallographic heavy atom analysis after its conversion to a synthetic derivative. Crystallographic analysis of xylindein crystallized with phenols revealed that the proposed structure is the proper tautomer in the crystals.
