ALKYLATION OF β-DICARBONYL COMPOUNDS BY 1,2,3-TRIHALOPROPANES AS A METHOD FOR THE PREPARATION OF β-SUBSTITUTED FURANS

Article abstract of DOI:10.1007/BF00474346

Alkylation of β-dicarbonyl compounds by 1,2,3-trihalides leads to a readily separable mixture of mono- and dialkylation products, and under more rigorous conditions, to 3-substituted 2,4-dimethylfurans.A similar reaction with propargyl bromide leads to furans with a "normal" structure, namely, 2,5-dimethylfurans.
