    An accelerated process for preparing a methyl ester having formula (III) 1 said process comprising reacting a carboxylic acid or salt thereof having formula (I) 2 with dimethyl carbonate having formula (II) 3 in the presence of a catalyst selected from the group consisting of 1,8-diazabicyclo[5.4.0]undec-7-ene; 1,4-diazabicyclo[2.2.2]octane; 4-dimethylaminopyridine; and combinations thereof, wherein R 1 is selected from the group consisting of an alkyl, aryl, alkoxy, alkenyl, cycloalkyl, benzocycloalkyl, cycloalkylalkyl, aralkyl, heterocyclic, heteroaralkyl, alkoxyalkyl, carboxyalkyl, alkylcarbonyl, alkoxycarbonyl, alkoxycarbonylalkyl, and haloalkyl; and M is selected from the group consisting of hydrogen, a monovalent metal, and a monovalent fractional part of a polyvalent metal, wherein said process is conducted under microwave irradiation at a frequency from 300 MHz to 30 GHz, and at a temperature of from about 120° C. to 300° C. for a period of microwave irradiation time from about 1 second to about 300 minutes. The process of the invention is especially advantageous for preparing methyl esters since the process: (1) utilizes an environmentally friendly methylating reagent, dimethylcarbonate; (2) produces a high yield of the methyl ester, generally 95-99% conversion in less than 30 minutes of microwave irradiation; (3) minimizes degradation and/or racemization of optically pure compounds; and (4) minimizes the formation of by-products.

  • Method of Inducing Chirality to Epoxides Using 2,3:4,6 di-O-isopropylidene-2-keto-L-gulonic Acid Monohydrate

    公开(公告)日:2010-06-03
    The present invention relates to a recyclable method to prepare chirally pure epoxides directly from olefins using a novel chiral acid 2,3:4,6-di-O-isopropylidene-2-keto-L-gulonic acid monohydrate as chiral inducer and anhydrous hydrogen peroxide in the form of urea hydrogen peroxide adduct (UHP) as oxidant and lipase enzyme as catalyst. Under the influence of lipase, the chiral acid 2,3:4,6-di-O-isopropylidene-2-keto-L-gulonic acid monohydrate is converted to per-acid in situ by the oxidant urea hydrogen peroxide which in turn transfers oxygen to olefin inducing chirality to the product epoxide. Using this technique, important epoxide building blocks of different industrially important compounds can be prepared with good yield and moderate enantioselectivity. Chiral epoxidation of olefins with environment friendly catalytic system that can be recycled is highly desirable in the context of Green Chemistry for preparation of many industrially important compounds.
