title: 2-Methyl-1-(phenyl-sulfon-yl)naphtho[2,1-b]furan.
abstract: The title compound, C(19)H(14)O(3)S, was prepared by the oxidation of 2-methyl-1-(phenyl-sulfan-yl)naphtho[2,1-b]furan with 3-chloro-peroxy-benzoic acid. The phenyl ring makes a dihedral angle of 87.13 (4)° with the plane of the naphthofuran fragment. The crystal structure is stabilized by π-π inter-actions between the furan and benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.850 (2) Å] and weak C-H⋯π inter-actions. In addition, there are also intra-molecular C-H⋯O inter-actions.
