CHEMISTRY OF OXALYL DERIVATIVES OF METHYL KETONES. XLVI. REACTION OF METHYL 3-METHYL- AND 3-BROMO-4-ARYL-2,4-DIOXOBUTYRATES WITH DIPHENYLDIAZOMETHANE

The reaction of methyl 3-methyl- and 3-bromo-4-aryl-2,4-dioxobutyrates with diphenyldiazomethane leads to the formation of methyl 3-methyl- and 3-bromo-4-aryl-2-diphenylmethoxy-4-oxo-2-butenoates.During the thermolysis of the latter the initially formed product from -sigmatropic rearrangement of the diphenylmethyl group undergoes further transformations
