✦ Synopsis

3-Arylpyrones and 5-arylpyrones featuring the 4-methoxy-2H-pyran-2-one moiety are obtained by Suzuki cross-coupling of the corresponding 3-iodo and 5-bromo derivatives with arylboronic acids.

The nearly planar molecule of the fungal metabolite infectopyrone, C 14 H 16 O 5 , with an r.m.s. deviation of 0.040 (2) A ˚from the plane through all atoms, is linked tail-to-tail by strong O-HÁ Á ÁO hydrogen bonds into dimers. Weaker C-HÁ Á ÁO hydrogen bonds link the pyran-2-one 'head' groups.
