IMPROVED METHOD OF OBTAINING PIPERITONE
Bazyl'chik, V. V.,Overchuk, T. N.
, p. 292 - 295 (1992)
A new convenient variant of the reduction of thymol methyl ether by lithium and isopropanol in the presence of ethylenediamine at 80-85 deg C and a molar equivalent ratio of ether to alcohol to amine to metal of 1:(8-12):(2.5-3):(4-6) has been developed.The proposed method permits the yield of piperitone to be doubled in comparison with known methods.
