Synthetic Route of 1679-47-6, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 1679-47-6, Name is 3-Methyldihydrofuran-2(3H)-one,introducing its new discovery.
Process for the preparation of alkyl 1-methylcyclopropanecarboxylate
Disclosed is a 4-step process for the preparation of alkyl esters of 1-methylcyclopropanecarboxylic acid which comprises the steps of (1) converting gamma-butyrolactone to alpha-methyl-gamma-butyrolactone; (2) converting the alpha-methyl-gamma-butyrolactone from step (1) to an alkyl 4-halo-2-methylbutyrate; (3) producing a xylene solution of the alkyl 4-halo-2-methylbutyrate; and (4) contacting the xylene solution of an alkyl 4-halo-2-methylbutyrate from step (3) with an alkali metal alkoxide under conditions of temperature and pressure which causes vaporization of (i) an alkanol as it is formed and (ii) an alkyl 1-methylcyclopropanecarboxylate as it is formed from the alkyl 4-halo-2-methylbutyrate. Also disclosed are processes whereby the alkyl 1-methylcyclopropanecarboxylate, prepared as described above, is converted to 1-methylcyclopropylamine.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 1679-47-6, and how the biochemistry of the body works.Synthetic Route of 1679-47-6
