実験手順: To a stirred mixture of 4-methoxy-4-methylpentanal (60 g, 0.46 mol) and ethyl acetoacetate (156 g, 1.2 mol) at 5° C. was added a 21% solution of piperidine in ethanol (4.1 mL). Further additions (4×18 mL) of the piperidine solution were made at about 24 hour intervals. The mixture was heated at reflux for 7 hours and concentrated to about 200 mL volume. Methanol (420 mL), water (420 mL) and sodium hydroxide (24 g) were added and the resulting mixture was heated at reflux 16 hours. Workup gave 3-(3-methoxy-3-methylbut-1-yl)-5-methylcyclohex-5-en-1-one bp0.1 135°-140° C. (69.2 g); NMR(CDCl3)δ1.2(s,6H), 0.9-1.6(m,5H), 1.9(s,3H), 5.9(brs,1H); IR(neat) 2975, 2930, 1675, 1640, 1380, 1080 cm-1 ; MS(m/e) 43, 73, 81, 109, 122, 163, 196. The mixture was heated at reflux for 7 hours concentrated to about 200 mL volume Methanol (420 mL), water (420 mL) and sodium hydroxide (24 g) were added the resulting mixture was heated at reflux 16 hours

実験手順: A stirred, cooled (-65° C.) mixture of 2,6-dimethyl-2-methoxyhept-5-ene (125 g, 1.25 mol), methylene chloride (500 mL) and methanol (500 mL) was treated with a gas stream enriched with ozone. Upon the appearance of a blue color pure oxygen was passed through the mixture followed by nitrogen. Dimethyl sulfide (88 mL, 1.4 mol) was added and the mixture was allowed to stand 16 hours at 25° C. Upon workup 4-methoxy-4-methylpentanal was obtained, bp30 85°-87° C.
