Convenient preparations of t-butyl esters and ethers from t-butanol

A one-pot preparation of t-butyl esters and ethers is described that proceeds from the carboxylic acid or alcohol and t-butanol using only anhydrous magnesium sulfate and catalytic sulfuric acid as additional reagents. The method affords t-butyl esters and ethers in good yields and is applicable to a variety of substrates.

A larene/ fragrant mixedsurrounds uncle butanol method for preparing ester compounds

The invention discloses a preparation method of an aromatic ring/aromatic heterocycle tert-butyl alcohol ester compound. The preparation method of the aromatic ring/aromatic heterocycle tert-butyl alcohol ester compound comprises the following steps of: firstly, under stirring condition, adding aromatic heterocycle borate compound or aromatic ring boric acid compound and di-tert-butyl dicarbonate ester into a solvent, and then adding a palladium catalyst and a ligand, so that a mixture A is obtained; secondly, heating the mixture A for carrying out reaction, and then cooling to room temperature, so that a mixture B is obtained; thirdly, diluting the mixture B with ethyl acetate, then filtering the diluted mixture B with diatomite, collecting filtrate, concentrating, and carrying out spin drying, so that the aromatic ring/aromatic heterocycle tert-butyl alcohol ester compound is obtained. The preparation method of the aromatic ring/aromatic heterocycle tert-butyl alcohol ester compound has the advantages that alkoxycarbonylation reaction on an aromatic heterocycle borate compound or aromatic ring boric acid compound is realized, and the aromatic ring/aromatic heterocycle tert-butyl alcohol ester compound is directly generated; raw materials are non-toxic, inexpensive and available; a catalytic system is low in cost and has good stability and broad applicability; reaction conditions are mild, safety is high, and control is easy; a technology is simple, operation is easy, environmental friendliness is realized, and specificity is strong, so that the preparation method of the aromatic ring/aromatic heterocycle tert-butyl alcohol ester compound is applicable to industrialized production.

Preparation of tert-butyl esters via Pd-catalyzed tert-butoxycarbonylation of (hetero)aryl boronic acid derivatives

A novel protocol to synthesize tert-butyl esters from boronic acids or boronic acid pinacol esters and di-t-butyl dicarbonate has been successfully achieved. The cross-coupling reactions can produce up to 94% yields by using palladium acetate and triphenylphosphine as catalyst system, dioxane as a solvent. Moreover, a wide range of substrates including benzenes, pyridines, and quinolines boronic acids or boronic acid pinacol esters can fit with this system as well.

Synthesis of functionalized aryl fluorides using organolithium reagents in flow microreactors

Flow on: Flow microreactors enable the generation of aryl lithium compounds and subsequent electrophilic fluorination with NFSI and N-fluorosultam. The reaction can be successfully accomplished to synthesize various aryl fluorides involving an electron-withdrawing, an electron-donating, and a sterically hindered functional group in good yields.
