Ethyl 3-(10-chloro­anthracen­yl)-5-(1-phenyl-2-hydroxy­ethen­yl)isoxazole-4-carboxyl­ate: an enol produced by Dess–Martin oxidation.

The title compound, C28H20ClNO4, is a very stable enol produced by a Dess–Martin oxidation, not the expected ketone. The enol form is stabilized by intra­molecular hydrogen bonding and the mol­ecules associate into dimers via weak C—H⋯N hydrogen bonding. [ABSTRACT FROM AUTHOR]
