Methoxy acetate

Normally ethyl acetate is used for the acylation of primary amines, in many cases, as acyl donor and solvent. Other acylating agents such as alkyl methoxy acetates are...

Die stereospezifische Synthese zu civ-Azo-Verbindungen mit Braunstein wurde in der Lit. beschrieben. Oberhalb 70° lagern sich die cis- in die /raws-Azo-Verbindungen um. Die Oxidation kann auch von aromatischen Aminen ausgehen. Die Ausbeuten der Reaktion sind sehr gut nur bei Hydrazinen mit konjugierenden /rara-Substituenten (Methoxy, Acet-oxy, Acetamino) werden die para-Azo-Verbindungen gcbildct3 vgl. aber auch S. 62. 

Methoxy acetates.—In view of the stronger complexation in glycolates compared to acetates one might expect the same behaviour for the methoxyacetate ion (CH3—O—CH2—COO-). However, the following log kn y = 0.1, at 20° C) values for the rare earth-methoxyacetate complexes [391] demonstrate that except for the heavier rare earths... 

A potent toxin produced by Penicillium islandicum has been characterized23 by mass spectroscopy combined with partial acid hydrolysis, and shown to possess structure (25). Three alkaloids isolated from the Egyptian plant Cent-aurium spicatum (which is used for the treatment of hypertension) are (26 R R2 = O), its methoxy-acetal (26 R1 = OH, R2 = OMe), and spicatine.24...

Kinetics of the formation of 2-methoxycarbonyl-5,7-dinitrobenzothiazole-3-oxide by cyclization of S-(2,4,6-trinitrophenyl)mercap(oacc(a(c in acetate, methoxy-acetate, or IV-methylmorfoline buffers has been studied [601], In the first two buffers the cyclization follows two reaction pathways, which differ in the order of reaction steps, with the proton splitting off from the C-H group being the rate-limiting step in either pathway (Scheme 2.110). 

Alkylation of cyclohexanone enamines with methyl chloro(methoxy)acetate, followed by alkaline hydrolysis, affords the y-keto acid 30, which readily cyclizes to the unsaturated lactone 31 on treatment with hydrogen chloride in acetic acid (equation 20)40. 

The pKo value, hypothetical and constant by its definition, is determinable by extrapolating the experimental pK pp values to intercept they coordinate at a = 0, where the polyelectrolyte effect has diminished to zero at a = 0. In the case of CmDx, the pKg value is estimated to be 3.20 as shown in Figs. 7 and 8, respectively. This value is quite close to the pK, value of methoxy acetic acid (pK, = 3.31, I = 0.1(NaClO4)) [58], the monomer analog of CmDx. Combining Eqs. (13) and (14), we obtain Eq. (15). 

The pK pp value resolved by the use of the H+ ion concentration in the gel phase, [H]g, now applies directly to the dissociation of the carboxylic acid moiety (methoxy acetic acid) repeated throughout the matrix of the CmDx gel.
