On water catalyst-free synthesis of benzo[: D] imidazo[2,1- b] thiazoles and novel N -alkylated 2-aminobenzo [d] oxazoles under microwave irradiation

A highly efficient unprecedented catalyst-free microwave-assisted procedure for synthesizing benzo[d]imidazo[2,1-b]thiazoles and N-alkylated 2-aminobenzo[d]oxazol in green media was developed. The transformation provided rapid access to functionalized benzo[d]imidazo[2,1-b]thiazoles from 2-aminobenzothiazole and N-alkylated 2-aminobenzo[d]oxazole from 2-aminobenzoxazole scaffolds under mild transition-metal-free conditions. This synthetic manipulation is expected to greatly expand the repertoire of reaction types in heterocyclic chemistry and pave the way for new syntheses of bioactive compounds.

ABSTRACT Ahighly efficient, simple and rapid method for the preparation of various 2-aminobenzoxazoles and other benzoxazole derivatives using a catalytic amount of poly (ethylene glycol)-bound sulphonic acid (PEG-SO3H) is described. PEG-SO3H is found to be economical and reusable catalyst with low catalytic loading. The percentage yield was found to be satisfactory, experimental set-up and purification of final products is facile and easy. GRAPHICAL ABSTRACT.

Copper-Catalyzed Three-Component Carboamination of Arynes: Expeditious Synthesis of o-Alkynyl Anilines and o-Benzoxazolyl Anilines

A copper-catalyzed three-component reaction of in situ formed arynes, terminal alkynes, and O-benzoylhydroxylamines has been developed. By adjusting reaction conditions, the nucleophiles in this transformation can be extended from terminal alkynes to benzoxazoles. These procedures provide a modular and facile approach to o-alkynyl anilines and o-benzoxazolyl anilines from easily available substrates in only one step.

Direct O-Acylation of Small Molecules Containing CO2(1-)—HN<*><--HO Units by a Distorted Amide: Enhancement of Amine Basicity by a Pendant Carboxylate in a Serine Protease Mimic The kinetics of the reaction of two series of amino alcohols (ethanol amines and 2-hydroxymethylimidazoles) with a distorted amide were studied as models for the acylation of the serine proteases.The pH/logk2max profiles plateau above the amine pKa, indicating the basic form is active.In all cases, the reactions proceed by initial O-acylation to produce esters.With primary or secondary ethanolamines, subsequent O-->N acyl transfer occurs to give amides.In each series, a Bronsted relationship exists relating the increasing amine pKa with an increasing second-order rate constant for O-acylation.Amino alcohols containing a pendant carboxylate (e.g., serine and the 4(5)- derivative of 2-hydroxymethylimidazole) fit on the Bronsted plots exactly, which suggests the amine pKa controls the reactivity.The role of the carboxylate is to enhance the amine basicity by electrostatic/inductive means.This is particularly effective in solvents of reduced polarity (40percent and 80percent v/v, EtOH/H2O) since the above effects counteract the normal drop in amine pKa exhibited by the other amino alcohols that do not possess the CO2(1-).Both series exhibit low kinetic solvent isotope effects of between 1 and 2.In the imidazole alcohol series, as the amine pKa increases the kinetic solvent isotope effect tends to 1.0.This is discussed in terms of a possible involvement of direct nucleophilic attack of an ammonium alkoxide zwitterion on 1.

Enantioselective Synthesis of Axially Chiral Biaryls via Copper-Catalyzed Thiolation of Cyclic Diaryliodonium Salts

Here, we report a chiral copper(II)-bisoxazoline-catalyzed enantioselective ring opening of cyclic diaryliodonium salts with heteroaryl thiols. The readily available 2-mercaptobenzoxazole and 2-mercaptobenzothiazole derivatives reacted efficiently with cyclic diaryliodonium salts and afforded various axially chiral biaryls bearing iodine and sulfur functional groups in excellent yields and enantioselectivities. The products were further transformed into diverse enantiopure alkyl biaryl sulfides, which can be employed as chiral ligands.
