摘要

It was shown formerly that 4-methyl-3, 4-dibromotetrahydropyran (I) in reactions with a number of nucleophiles formed in succession products of dehydrobromination and substitution, dihydropyrans III [133]. In performing similar reactions with enolates of b- dicarbonyl compounds we revealed an unusual process: formation of [dehydrodimers] V of the initial dicarbonyl compounds. For instance, from malonic ester malonylmalonic ester ( ...
