- a 2-necked 1,3-propanediol 26.86 g (298 mm o 1) and sulfuric acid 8 were placed in a 10-Om 1 four-necked flask equipped with a stirrer, thermometer, and dropping funnel. 2 g (82 mm o 1), and then a solution of 10 g (74.6 mm o 1) of sodium formylcyclopropyl methyl ketone dissolved in 20 g of methanol was heated to an internal temperature of 25 ° C with stirring. For 1 hour. After completion of the dropwise addition, the internal temperature was raised to 60 ° C., and the mixture was further stirred for 1 hour.
- the obtained reaction mixture was added to 40 g of a saturated aqueous solution of sodium hydrogen carbonate, and the organic layer and the aqueous layer were separated.
- the obtained organic layer was analyzed by gas chromatography to find that it contained 9.92 g of 2- (2-cyclopropyl-12-oxoethyl) -5-methyl-1,3-dioxane. Rate 72%).
- the residue was distilled over 5 OPa to give 2- (2-cyclopropyl-12-oxoethyl) -15-methyl-1,3 as a 91-92 ° C fraction. —9 llg of dioxane was obtained.
- a 100 ml four-necked flask equipped with a stirrer, thermometer, and dropping funnel was charged with ethylene glycolone (7.88 g, 298 mm o 1) and sulfuric acid 8.2 g (82 mm, Then, a solution prepared by dissolving 10 g (74.6 mmo 1) of sodium formylcyclopropyl methyl ketone in 20 g of methanol was stirred at an internal temperature of 25 ° C for 1 hour. The solution was dropped.
- quinolin carbaldehyde useful as a synthetic intermediate for pharmaceuticals, agricultural chemicals, etc. are useful as intermediates in the synthesis of quinoline-based mevalonolactone derivatives known as inhibitors of HMG-C0A reductase, which is the rate-limiting enzyme in cholesterol biosynthesis.
