Reactions of diazo ketones with activated unsaturated compounds in the presence of gallium trichloride

Diazoacetone reacts with methyl acrylate in the presence of anhydrous GaCl3 to give isomeric methyl 2-acetylcyclopropanecarboxylates rather than pyrazolines obtained from diazo esters or by noncatalytic reactions. In a similar reaction, diazoacetophenone yields methyl 2-benzoylcyclopropanecarboxylates, benzoylmethyl acrylate, and benzoylmethyl 2-benzoylcyclopropanecarboxylate via partial transesterification. Addition of an equimolar amount of GaCl3 to diazoacetone in the system CH2Cl2-HCl-H2O unexpectedly produces 4,5-dimethylfuran-3(2H)-one and 1,1'-oxybis(propan-2-one).
