Abstract:

A three-component reaction of β,γ-unsaturated α-keto esters, proline, and dialkyl maleates has been developed. This reaction provides pyrrolizidine derivatives containing three ester groups and a styrenyl group, as well as a quaternary center, in moderate to good yields and with good to excellent diastereoselectivities.

Abstract:

3,3-Dialkyl-3H-pyrazole-4,5-dicarboxylic acid dimethyl esters (4), obtained by cycloaddition of R1R2C=N+=N− (R1 = R2 = CH3; R1 = CH3, R2 = CH2CH3) to CH3O2CC≡CCO2CH3, rearrange thermally by 1,5-sigmatropic alkyl shifts to both N and C. The latter rearrangement is followed by two successive 1,5-sigmatropic shifts of a methoxycarbonyl group. Final products of the threefold rearrangement were shown to be 4,5-dialkyl-1H-pyrazole-1,3-dicarboxylic acid dimethyl esters (6), rather than the isomeric 3,4-dialkyl-1H-pyrazole-1,5-dicarboxylic acid dimethyl esters (7), by means of single crystal X-ray dif

Purpose The phosphorus and zinc contained in zinc dialkyl dithiophosphate (ZDDP) caused severe environment pollution and catalyst poison.

ABSTRACT Phthalate esters (PEs) are important environmental pollutants. While the biodegradation of the parent compound, phthalate (PTH), is well characterized, the biodegradation of PEs is not well understood. In particular, prior to this study, genes involved in the uptake and hydrolysis of these compounds were not conclusively identified. We found that Rhodococcus jostii RHA1 could grow on a variety of monoalkyl PEs, including methyl, butyl, hexyl, and 2-ethylhexyl PTHs. Strain RHA1 could not grow on most dialkyl PEs, but suspensions of cells grown on PTH transformed dimethyl, diethyl, dipr

Moreover, in the presence of [emim][HSO4], the reaction could be performed to afford the phosphonic esteracid with a selectivity of 66% and the diacid with a selectivity of 97%.

Modification at the anomeric position, leading mainly to anomeric esters or glycosides, is of particular importance in the glycosciences.

Abstract:

Functionalized 2-indolizin-3-yl-1,3-benzothiazoles were obtained in moderate yields from the reaction between 1-(1,3-benzothiazol-2-ylmethyl)pyridinium iodide and acetylenic esters in acetonitrile. When isoquinoline was used under similar conditions, dialkyl 3-(1,3-benzothiazol-2-yl)pyrrolo[2,1-a]isoquinoline-1,2-dicarboxylates were obtained. The structures of these products have been confirmed by X-ray diffractometry.

Abstract:

A catalytic enantioselective α-amination reaction of alkenoate cyclic esters with dialkyl azodicarboxylates was achieved by using a 3,3′-di(1-naphthyl)-substituted (R)-BINOL–dibromostannane complex as a chiral precatalyst in the presence of a sodium alkoxide and an alcohol. Optically active α-hydrazino ketones were obtained in moderate to high yields and with up to 91% ee in the presence of the chiral tin alkoxide generated in situ.

Abstract:

Two new continuous flow systems for the production of dialkyl succinates were developed via the esterification of succinic acid, and via the trans-esterification of dimethyl succinate. The first microwave-assisted continuous esterification of succinic acid with H2SO4 as a chemical homogeneous catalyst was successfully achieved via a single pass (ca 320 s) at 65–115 °C using a MiniFlow 200ss Sairem Technology. The first continuous trans-esterification of dimethyl succinate with lipase Cal B as an enzymatic catalyst was developed using a Syrris Asia Technology, with an optimal reaction condition

Abstract:

The McKenna reaction is a well-known and popular method for the efficient and mild synthesis of organophosphorus acids. Bromotrimethylsilane (BTMS) is the main reagent in this reaction, which transforms dialkyl phosphonate esters into bis(trimethylsilyl)esters, which are then easily converted into the target acids. However, the versatile character of the McKenna reaction is not always used to its full extent, due to formation of side products. Herein, demonstrated by using model examples we have not only analyzed the typical side processes accompanying the McKenna reaction, but also uncovered

Abstract:

For the usage of dialkylphosphate as a gelatinizer in oil based fracturing fluid, there are two methods of preparation involved: 1.The improved ethylphosphate method is used to control one of the ester chains by using single alcohol substitute for mixed alcohols; 2.The new method of polyphosphate is used to control both of ester chains. Different kinds of alcohols are used as the raw materials in 3?3 orthogonal experiment (ratio of reactants, reaction temperature and reaction time) to obtain the optimum reaction conditions. Furthermore, 14 kinds of gelatinizers are produced by these experiment
