Investigation of reaction of dimedone and ethyl acetoacetate with 1,2-epoxy-3-chloropropane
摘要:
Reactions of dimedone and ethyl acetoacetate with 1,2-epoxy-3-chloropropane in the presence of K2CO3 in DMSO medium were investigated. The reaction of 1,2-epoxy-3-chloropropane with ethyl acetoacetate afforded ethyl 5-hydroxy-2-methyl-5,6-dihydro-4H-pyran-3-carboxylate, with dimedone, 3-(1', 2'-epoxy propyloxy)-5,5-dimethyl-cyclohex-2-en-1-one.
