Investigation of the reaction of (chlorocarbonyl)mesitylketene with ketones
led to the discovery of a new synthetic pathway which yields 4-hydroxy-3-m
esityl tetronic acids. Depending on the reaction conditions and the substit
ution pattern of the starting ketone, the expected products, i.e. 4-hydroxy
-3-mesitylpyrones, can nevertheless be obtained. (C) 2001 Elsevier Science
