5-Hydroxy-2-methyl-4H-pyran-4-one
The title compound, C6H6O3, is a member of the pyrone family. The molecules are planar (r.m.s. deviation of the asymmetric unit is 0.0248 Å, whereas that of the dimer is 0.0360 Å) and they are dimerized due to intermolecular O—

Synthesis of an Antileukemic Pyrone from
Antileukemic pyrone 1 was synthesized by way of a five-step procedure from 4 -Hydroxy-5-methoxycarbonyl-6-methyl-2-pyrone (8). This is the first synthesis of 4-methoxy-6-methyl-5-(3-oxobutyl)-2H-pyran-2-one (1).

Nocapyrones: α- and γ-Pyrones from a Marine-Derived Nocardiopsis sp.
One new α-pyrone (nocapyrone R (1)), and three known γ-pyrones (nocapyrones B, H and L (2–4)) were isolated from the culture extract of a Nocardiopsis strain collected from marine sediment.
