Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 37722-82-0, name is Methyl 3-Hydroxycyclohexanecarboxylate, A new synthetic method of this compound is introduced below., Formula: C8H14O3
Methyl 3-oxocvclohexanecarboxylateRuthenium (IV) oxide hydrate (1.47 g, 1 1.1 mmol) and sodium bromate (100 g, 664 mmol) were combined in diethyl ether (600 mL) and water (300 mL). The resulting black mixture was stirred for 10 min and then cooled in an ice bath. Methyl 3- hydroxycyclohexanecarboxylate (35 g, 221 mmol) was dissolved in ether (to bring total volume to 100 mL) and was added dropwise to the ice cold reaction mixture. The temperature was not allowed to go above 30 C. The reaction mixture was stirred for 1 h with the reaction temperature at -15 C. Isopropanol was carefully added to the reaction mixture at a rate necessary to keep the reaction temperature at -27 C. The layers were separated and the organic layers were washed with ether. The combined organics were washed with saturated aqueous NaHC03 solution and brine. The organics were then dried over MgS04, filtered, and concentrated to provide methyl 3-oxocyclohexanecarboxylate (34.5 g, 100 % yield) which was used without further purification. H NMR (400 MHz, CDCI3) delta 3.68 (s, 3H), 2.79 (m, 1 H), 2.52 (d, J = 7.78 Hz, 2H), 2.23 – 2.42 (m, 2H), 1.98 – 2.15 (m, 2H), 1.82 (d, J = 10.29 Hz, 1 H), 1.61 – 1.77 (m, 1 H).
The synthetic route of 37722-82-0 has been constantly updated, and we look forward to future research findings.
