Oximation of oreoselone to produce a mixture the E- and Z-oximes was investigated. The crystal and Molecular structures of oreoselone Z-oxime and the Beckmann rearrangement product of oreoselone E- or Z-oximes and PCl5,7-(1-chloro-2-methylpropoxy)-2-oxo-2H-1-benzopyram-6-carbonitrile, were established by XSA. Hydrolysis of the latter produced 7-hydroxy-2-oxo-2H-1-benzopyran-6-carbonitrile.
