Physicochemical characterization of new sulfonate and sulfate ammonium ionic liquids

In this work we describe the synthesis and thermal properties of nine new salts derived from ammonium that incorporate alkanesulfonate and alkanesulfate anions. Their structures were confirmed by 1H and 13C NMR and HRMS-ESI. Their thermal properties were determined by differential scanning calorimetry (DSC). Three of the synthesized salts have been shown to be room temperature ionic liquids: N-ethyl-N-(2-hydroxyethyl)-N,N-dimethylammonium butanesulfonate, N-ethyl-N,N-dimethylbutylammonium ethylsulfate, and N-ethyl-N-(2-hydroxyethyl)-N,N-dimethylammonium ethylsulfate. Experimental densities, speeds of sound, dynamic viscosities, and refractive indices of these three ionic liquids were measured at T = 298.15 K.

PROCESS FOR PRODUCTION OF SULFONIC ACID ESTER

The present invention provides a method for producing a sulfonate ester efficiently and in high yield. The present invention is an invention of a method for producing a sulfonate ester compound, which comprising reacting: (a) a compound having a sulfo group (-SO3H); and (b) a compound having a group represented by the general formula [1]: ????????-OR1?????[1] [wherein, R1 represents a sulfonyl group represented by the general formula [2]: ????????-SO-R2?????[2] (wherein, R2 represents a halogen atom, a haloalkyl group, an alkoxy group, or an optionally substituted alkyl group or an optionally substituted aryl group) or an acyl group represented by the general formula [3]: (wherein, R3 represents an optionally substituted alkyl group or an optionally substituted aryl group)]; in the presence of an organic base which is capable of forming a salt with said sulfo group.

Foldamers as reactive sieves: Reactivity as a probe of conformational flexibility

A series of m-phenyleneethynylene (mPE) oligomers modified with a dimethylaminopyridine (DMAP) unit were treated with methyl sulfonates of varying sizes and shapes, and the relative reactivities were measured by UV spectrophotometry. Using a small-molecule DMAP analogue as a reference, each of the methyl sulfonates was shown to react at nearly identical rate. In great contrast, oligomers that are long enough to fold, and hence capable of binding the methyl sulfonate, experience rate enhancements of 18-1600-fold relative to that of the small-molecule analogue, depending on the type of alkyl chain attached to the guest. Three different oligomer lengths were studied, with the longest oligomers exhibiting the fastest rate and greatest substrate specificity. Even large, bulky guests show slightly enhanced methylation rates compared to that with the reference DMAP, which suggests a dynamic nature to the oligomer's binding cavity. Several mechanistic models to describe this behavior are discussed.

Antidiabetic agents

The present invention provides compounds of Formula (I): wherein A, X, Q, Y, B, D, Z, and E have any of the values defined in the specification, and pharmaceutically acceptable salt thereof, that are useful as antidiabetic agents.

Process for preparation of oxyglutaric acid ester derivatives

A process for preparing an oxyglutaric acid ester derivative of the formula: STR1 in which each of R1 and R2 is C1-5 alkoxy, C1-7 aralkyloxy, C7-9 halogenated aralkyloxy or phenyl, R4 is a hydroxyl-protecting group, and R5 is C1-10 alkyl which may have a substituent, comprises the steps of reacting a methyl phosphonate derivative or methyl phosphine oxide derivative with an oxyglutaric acid mono-ester to give a reaction product which comprises an oxyglutaric acid derivative having a phosphorus-containing group and a pentenedioic acid mono-ester (by-product), removing the pendenedioic acid mono-ester from the reaction product to isolate the oxyglutaric acid derivative, and converting the isolated oxyglutaric acid derivative into the oxyglutaric acid ester derivative. A process for obtaining an optically active oxyglutaric acid ester derivative is also disclosed.
