Abstract

In the title mol-ecule, C(13)H(16)O(4), the pyran ring is in a half-chair conformation. There is an intra-molecular hydrogen bond involving the ketone O atom and an H atom of a phenol group which forms an S(6) ring. The ketone O atom is also involved in an inter-molecular hydrogen bond with a different phenolic H atom of a symmetry-related mol-ecule, forming C(6) chains along the c-axis direction.
