AMINATION AND HYDROXYLATION OF ARYLMETAL COMPOUNDS

In one aspect, the present disclosure provides methods of preparing a primary or secondary amine and hydroxylated aromatic compounds. In some embodiments, the aromatic compound may be unsubstituted, substituted, or contain one or more heteroatoms within the rings of the aromatic compound. The methods described herein may be carried out without the need for transition metal catalysts or harsh reaction conditions.

Ruthenium(III) acetylacetonate [Ru(acac)3] - An efficient chemoselective catalyst for the tetrahydropyranylation (THP) of alcohols and phenols under solvent-free conditions

A catalytic amount of ruthenium(III) acetylacetonate (2 mol%) [Ru(acac)3] enables solvent-free tetrahydropyranylation of different types of alcohols and phenols at ambient temperature in moderate to excellent yields. Notably, selective monoprotection of diols can be achieved chemoselectively. Furthermore, the catalyst could be recovered and reused if necessary.

Selective tetrahydropyranylation under non-acidic conditions

We report that the tetrahydropyranylation of hydroxyl groups, exhibiting especially very low nucleophilicities, can be achieved by means of Mitsunobu reaction with 2-hydroxytetrahydropyran. This reaction led to the protection of phenols and pyridinols without the use of an acidic catalyst. For instance hydroxypyridines could not be protected by dihydropyran under acidic conditions, whereas they underwent a smooth tetrahydropyranylation under Mitsunobu conditions. The method is selective for a phenol over an alcohol. Georg Thieme Verlag Stuttgart.

Design and synthesis of an α,α-difluorophosphinate hapten for antibody-catalyzed hydrolysis of organophosphorus nerve agents

In a new approach to the safe neutralization of organophosphorus chemical weapons, we designed a hapten to elicit catalytic antibodies with phosphatase activity. Here we report the synthesis of this α,α- difluorophosphinate hapten 6. Various methods for t

Synthesis and properties of N(α)-(tert-butyloxycarbonyl)peptide p- guanidinophenyl esters as trypsin substrates

N(α)-(tert-Butyloxycarbonyl)peptide p-guanidinophenyl esters were synthesized by amidination of N(α)-(tert-butyloxycarbonyl)peptide p- aminophenyl esters with 1-[N,N'-bis(benzyloxycarbonyl)amidino]pyrazole, followed by deprotection by catalytic hydrogenation, in good total yields. These synthetic esters were characterized as specific substrates for trypsin, and kinetic parameters for the trypsin-catalyzed hydrolysis are presented.
