Crystal structure of 3-(4-methoxyphenyl)-2,3-dihydro-1H-naphtho[2,1-b]pyran-1-one
In the title compound, C20H16O3, the hydropyran ring adopts a distorted half-chair conformation with the methine C atom and the ring O atom displaced by −0.554 (2) and 0.158 (1) Å, respectively, from the plane of the other four atoms (r.m.s. deviation = 0.020 Å). Its mean plane (all atoms) is inclin...
