2-Methoxy-1-naphthaleneboronic acid is a ligand for asymmetric synthesis. It is used in the demethylation of carbinols and halides to produce enantiopure carbinols and halides. The compound is also used as a chiral auxiliary in the kinetic resolution of racemic carboxylic acids to produce optically pure acids. In addition, 2-methoxy-1-naphthaleneboronic acid has been shown to be an effective catalyst for the catalytic asymmetric cross coupling of aldehydes with trifluoromethanesulfonate (triflate). The crystal structures of this compound have been determined by x-ray crystallography. 2-Methoxy-1-naphthaleneboronic acid is prepared by treating naphthaldehyde with boric acid in ethanol at refluxing temperature.

R-Acetylmandelic acid is an organic compound that is a racemic mixture of two enantiomers. It is an intermediate in the biosynthesis of succinic acid and it can be used to produce other chiral compounds. R-Acetylmandelic acid can be obtained from the human body and urine or synthesized from propionic acid. The structure of this molecule contains both carboxylic acid and amine functional groups, which are often used as reagents for derivatization reactions. The chirality of R-Acetylmandelic acid can be determined using analytical methods such as gas chromatography or high performance liquid chromatography. This compound is known to have a purity level of 99%.

Prepare 4-phenylurazole from ethyl carbazate and then oxidize the urazole with gaseous dinitrogen tetroxide to yield 4-phenyl-1,2,4-tri- azoline-3,5-dione la. Modification of the ethyl carbazate procedure in which analytically pure monoalkylhydrazine hydrochlorides were isolated in greater than 90% yield, starting from a ketone or aldehyde. Treatment of primary amines is with chloroamine or hydroxylamine-0-sulfonic acid and the condensation of a carbonyl compound with ethyl carbazate. The FeCl 3 -catalyzed reaction of ethyl carbazate (2 b) proceeded readily to give β-hydroxyester 3 b in better yield. A new one-pot neat synthesis of some 5-aryl-2,4-dihydro-3H-1,2,4-triazol-3-ones through cyclocondensation of ethyl carbazate with aryl nitriles catalyzed by DMAP as an efficient and basic nucleophilic catalyst is described.This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio.
