5-Hy­droxy-8,8-dimethyl-10-(2-methyl­but-3-en-2-yl)-2H,6H-7,8-dihydro­pyrano[3,2-g]chromene-2,6-dione

In the title compound, C(19)H(20)O(5), the pyran ring is in an envelope conformation, whereas the benzene and dihydro­pyran ring system is planar with an r.m.s. deviation of 0.0190 (1) Å. The hy­droxy group is coplanar with the attached benzene ring [r.m.s. deviation = 0.0106 (1) Å]. An intra­molecu...

description In the title compound, C(19)H(20)O(5), the pyran ring is in an envelope conformation, whereas the benzene and dihydro­pyran ring system is planar with an r.m.s. deviation of 0.0190 (1) Å. The hy­droxy group is coplanar with the attached benzene ring [r.m.s. deviation = 0.0106 (1) Å]. An intra­molecular O—H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, mol­ecules are linked into chains along the b axis by weak C—H⋯O inter­actions. These chains are stacked along the a axis. C—H⋯π and weak π–π inter­actions [centroid–centroid distance = 3.7698 (7) Å] are also observed.
