1,6,6-Trimethyl-1H-chromeno[6,7-d]thia-zol-2(6H)-one.

ABSTRACT: The title compound, C(13)H(13)NO(2)S, was prepared by a thermocyclization reaction from 3-methyl-6-(2-methyl-but-3-yn-2-yl-oxy)benzo[d]thia-zol-2(3H)-one. In the crystal structure, the methyl-thia-zole unit is planar, while the pyran ring assumes a screw-boat conformation. Intra-molecular C-H⋯O hydrogen bonding helps to stabilize the molecular structure.
