Abstrakt: |
Transesterification with subsequent cyclization to 4-carbethoxy-5,6,6-trialkyl-3-hydro-2-pyrones occurs during condensation of a-keto alcohols with diethyl succinate. 4-Carbethoxy-5,6,6-trimethyl-3-hydro-2-pyrone was obtained by reaction of dimethylethynylcarbinol with the ethyl ester of succinic acid monochloride and subsequent hydration of the acetylenic ester and cyclization. |
