A new synthesis of 2-allyl-4-hydroxy-3-methyl-2-cyclopenten-1-one, so called allethrolone is described, in which the Michael addition of 3-phenylthio-5-hexen-2-one to 1-nitro-1-propene followed by conversion of the nitromethyl group in the adduct to an aldehyde function is involved as the key step.
