3-Benzyl-2-(furan-2-yl)-1,3-thiazolidin-4-one
In the title compound, C(14)H(13)NO(2)S, the thia-zolidine ring is approximately planar with a maximum deviation of 0.112 (1) Å. The furan ring is disordered over two orientations, with an occupancy ratio of 0.901 (5):0.099 (5). The central thia-zolidine ring makes dihedral angles of 85.43 (8), 87.50 (11) and 87.9 (9)° with the phenyl ring and the major and minor components of the disordered fu...
