Convenient one-pot synthesis of 2-oxazolines from carboxylic acids.
Simple one-pot methods for preparation of 2-oxazolines have been developed using 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride (DMT-MM). Treatment of a mixture of carboxylic acids and 2-haloethylammonium salts with DMT-MM in methanol followed by refluxing in the presence of KOH gives oxazolines.

متن کاملZirconium Dodecylphosphonate: Selective and Constructive Catalyst for Preparation of 2-Alkyl Benzoxazoles from Aliphatic Carboxylic Acids
In this study, zirconium dodecylphosphonate was synthesized by the reported method in scientific literature. 2-Alkylbenzoxazoles were prepared from aliphatic carboxylic acids and 2-aminophenol in the presence of this catalyst under solvent-free conditions at 100°C. Their structures were recognized by IR, 1H NMR, and 13C NMR. Then, we used aromatic carboxylic acids in t...
متن کاملAn efficient one-pot synthesis of α-amino nitriles using ecofriendly Lewis-acidic ionic liquid choline chloride.2ZnCl2
α-Amino nitriles are synthesized in a one-pot, three-component coupling of aldehydes (or ketones), aniline, and trimethylsilyl cyanide using a catalytic amount of choline chloride.2ZnCl2 as a bio Lewis acidic ionic liquid. Mild Lewis acidic characteristic of this ionic liquid allows efficient synthesis of α-amino nitriles from acid sensitive aldehydes.
