Abstract

Abstract La condensation d'hydroxymethyl-5 furfural ou d'aldéhydes furanniques dérivés avec des composes car-bonylés ou sulfonés éthyléniques permet l'obtention de dérivés de la butanedione-1, 4 dont la cyclisation conduit á des di-et terfurannes substitues ou non. Abstract Addition of α, β-unsaturated sulfones or ketones to 5-hydroxmethyl-furaldehyde or related furanaldehydes in the presence of a thiazolium salt gives di or tetraketonic furan ...
