One pot direct synthesis of amides or oxazolines from carboxylic acids using Deoxo-Fluor reagent

A mild and highly efficient one pot–one step condensation and/or condensation–cyclization of various acids to amides and/or oxazolines using Deoxo-Fluor reagents is described. Parallel syntheses of various free fatty acids with 2-amino-2,2-dimethyl-1-propanol resulted with excellent yields.
