2-(2-Hydroxypropan-2-yl)-6-(prop-2-ynyloxy)-1-benzofuran-3(2H)-one

Abstract

In the title compound, C14H14O4, the prop-2-ynyloxy O—C—C[triple-bond]C plane [maximum deviation = 0.0116 (12) Å] forms a dihedral angle of 78.44 (9)° with the benzofuran-3(2H)-one ring system. In the crystal, molecules are linked by O—H...O hydrogen bonds, forming a tape along the a-axis direction. C—H...O interactions are observed between the tapes.
