Acid-Catalyzed Hydrolysis of Methoxymethyl Phenyl Sulfoxide without Concomitant Racemization

Kinetics of Formic Acid-catalyzed Cellulose Hydrolysis

Hydrolysis is a reaction to produce sugars from lignocellulosic raw materials for biochemical production. The present study elucidates the hydrolysis of cellulose and formation of glucose decomposition products catalyzed by 5% to 20% (w/w) formic acid at 180 to 220 °C with an initial cellulose concentration of 10 to 100 g/L. Microcrystalline cellulose was used as a model compound. The experimen...

Amino Acid Racemization

Reactivity of plasmalogens: kinetics of acid-catalyzed hydrolysis.

The acid-catalyzed hydrolysis of the alpha,-unsaturated ether group of two plasmalogens, lysophosphatidal choline and lysophosphatidal ethanolamine, and several model compounds (isobutyl vinyl ether, 1-butenyl ethyl ether, and dihydropyran) was studied by determining the true second-order rate constants. The results indicate that the chemical reactivity of the substituted vinyl ether group in p...

AuBr3-catalyzed thiooxime-to-carbonyl conversion: from chiral aliphatic nitro compounds to ketones without racemization.

A new variant of the NO(2)-to-CO transformation (the Nef reaction) that occurs at room temperature under neutral conditions is uncovered. After the conversion of secondary nitroalkanes to phenylsulfenylketimines, these thiooximes are hydrolyzed quantitatively in situ, in THF-H(2)O at pH 7, by addition of AuBr(3) (but not with other MX(n)!). Adducts arising from asymmetric nitro-Michael and nitr...
