Abstract

PURPOSE: Title compound, a synthetic intermediate of a perfume, is produced by treating inexpensive 6-methyl-5,6-epoxyheptanone-2 with an acid.
CONSTITUTION: 6-Methyl-5,6-epoxyheptanone-2 of formula II is treated with an acid as sulfuric or perchloric acid to produce 2-methyl-3,6-heptanedoine of formula I. The starting material of formula II is readily prepared by treating methylheptenone of formula III with peracetic acid.
USE: A synthetic intermediate for 3-isopropyl-2-cyclopentenone or sabinene hydrate.
