Structure-Odor Correlation, V. - From Menthone to Shyobunone - Change of Odor with Structure

Derivatives of menthone (4) were prepared by substitution at C-2 or C-3 whereby increasing similarity with the shyobunones (1, 2) should be achieved.Thus, the 3,3-disubstituted ketones 5-11 were synthesized by 1,4-addition to piperitone(3).The ketones 18 and 19 substituted at C-2 were prepared via the silyl ether 15.Analogously the ketones 22-25 have been synthesized.The ketones 28 and 29 were obtained from 15 via the diketone 20 and the aldol 21. - Key compound for the synthesis of 43 and 44 as well as 1 and 2 by 1,4-addition was the known ketone 40.While preparing 40 the side products 41 and 42 have also been obtained.The olfactory properties of the substituted menthones change stepwise from the minty odor of 4 by addition of spicy and woody notes up to those of 1 and 2 which possess a fruity-earthy-woody odor.
