Chupakhin // Russian Chemical Reviews. - 2001. - Vol. 70, № 11. - P921-938. - Bibliogr. : p. 938 (191 ref.) Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: Methods of synthesis of (het)aroylpyruvic acids and their acyclic derivatives (esters, amides and hydrazides), and their reactions with various C-, N-, O-, S-nucleophiles are described. Problems of tautomerism and biological activity of (het)aroylpyruvates and products of their transformation are briefly considered |
