bromoacetyl derivatives were usedfor alkylation of acetoacetic ester and cyclohexan-1,3-dione. Reaction of1,4-diketone prepared from acetoacetic ester with hydrazine hydrate in ethanolat room temperature leads to formation of furylpyrazines due to aromatization ofintermediate azines by means of air oxygen.

Chloromethylfuroyl chlorides react with alkyl glycinates and beta-alanates to form the corresponding chloromethylfuroyl amides. The compounds obtained are phosphorylated with triethyl phosphite under the conditions of the Arbuzov reaction to give (diethoxyphosphorylmethylfuroyl amides. Alkaline hydrolysis of these compounds proceeds only at the carboxy group leading to (diethoxyphosphorylmethyl)furoylglycine and furoyl-beta-alanine. Selectivity of hydrolysis does not depend on the position of carboxamide and diethoxyphosphorylmethyl groups in the furan ring.

Approaches to the synthesis of a wide range of phosphorylated derivatives of 3-(furyl)acrylic acid and 4-(furyl)buten-2-one with various functional groups in the furan ring have been developed.
