| abstract | PURPOSE:To obtain the titled compound useful as a tobacco flavor, in high purity and yield on an industrial scale with simple procedure, by using a specific raw material compound derived from piperitone and reacting the compound in the presence of cuprous chloride. CONSTITUTION:The objective compound of formula II can be produced by reacting 5-isopropyl-8-methyl-8,9-dihydroxy-6-nonyn-2-one of formula I in the presence of cuprous chloride preferably at 100-150 deg.C for 1-3hr. The starting compound of formula I is obtained by reacting 5-isopropyl-6-heptyn-2-one formula III derived from piperitone with ethylene glycol in the presence of an acid catalyst, reacting the reaction product with chloroacetone in the presence of butyllithium and contacting the resultant 5-isopropyl-8-methyl-2-ethylenedioxy-8,9- epoxy-6-nonyne of formula IV with a acid. |
