Ökonomische Herstellung von Feinchemikalien: Tetronsäure
Tetronic acid (1) is synthesized from ethyl 2,4-dichloroacetoacetate (11) via 3-chlorotetronic acid (9). Ring closure of 11 to 9 is achieved by pyrolysis at normal pressure. In contrast to the bromo-derivative 8, the catalytic conversion of 9 to 1 takes place in water in the absence of base. In thi...
