Meldrum's acid in heterocyclic synthesis: Azoles incorporating a 2,4-dichlorophenoxy moiety with anticipated molluscicidal activity

Article abstract of DOI:10.1007/s00706-007-0802-3

Synthesis of the title ring system is described using ethyl 4-(2,4-dichlorophenoxy)-3-oxobutanoate as starting material. The latter was prepared through acylating Meldrum's acid with the phenoxy acid chloride derivative.
