Tsuboi, Sadao published the artcileNew synthesis of (±)-menthofuran, Recommanded Product: Ethyl 2-Iodopropionate, the publication is Journal of Organic Chemistry (1980), 45(8), 1517-20, database is CAplus.
(±)-Menthofuran [(±)-I] was prepared in 3 steps from Et 4-methyl- 2-oxo-1-cyclohexanecarboxylate (II) in a reasonable overall yield. Reaction of II with MeCHICO2Et gave Et 2-(1-ethoxycarbonyl-4-methyl-2-oxocyclohexyl)propionate, which was converted directly to 3,6-dimethyl-2,4,5,6,7,7a-hexahydro-2-benzofuranone (III) by refluxing with concentrate HCl; reduction with LiAlH4-Me2CHOH at -60 to -50° gave (±)-I. The reduction of III at room temperature gave 2-(4-methyl-1-cyclohexenyl)-1,2-propanediol.
Journal of Organic Chemistry published new progress about 31253-08-4. 31253-08-4 belongs to iodides-buliding-blocks, auxiliary class Iodide,Ester, name is Ethyl 2-Iodopropionate, and the molecular formula is C17H14F3N3O2S, Recommanded Product: Ethyl 2-Iodopropionate.
