Dehydrating this compound forms an oxazole in the Robinson-Gabriel synthesis, and zinc compounds are used to generate them from thioesters in the Fukuyama coupling. Another reaction used to generate them uses thorium oxide to cyclize a dicarboxylic acid. Another method to create them uses a Lewis acid to create an acyl cloride, which undergoes an electrophilic aromatic substitution. In addition to the Ruzicka cyclization and the Friedel-Crafts reaction, these compounds can be created from secondary alcohols using the Jones reagent. They exist in an equilibrium with enols in a simple form of tautomerism. For 10 points, name these carbonyls that contain a carbon double bonded to an oxygen bound to two R groups.
