Anhydro-acylation of l,2-dihydro-2-oxo-l-pyridylacetic acid with acid anhydrides yields bicyclic meso-ionic 4-acyl-l,3-oxazol-5-ones (67). Huisgen and his co-workers have reported extensive studies of the monocyclic meso-ionic l,3-oxazol-5-ones (66), which they have lightheartedly named munchnones. Cyclodehydration of N-benzoyl-A -methyl-C-phenylglycine using acetic anhydride at 55° gives the 3-methyl-2,4-diphenyl derivative (66, R = = Ph R = Me) as...

An acyl chloride such as benzoyl chloride can react with secondary and primary amines and amino acids to form N-substituted benzamide derivatives. Analytical reagents used for precolumn derivatizations are p-nitrobenzene azobenzoyl chloride for LC-UV, o-acetylsalicyloyl chloride for LC-ECD, and 3,4-dihydro-6,7-dimethoxy-4-methyl-3-oxoquinoxa-line-2-carbonyl chloride (DMEQ-COCl) and 4-(4,5-diphenyl-lf/-imidazol-2-yl)benzoyl chloride (DIB-Cl) for LC-FL, respectively. Pentafluorobenzoyl chloride (PFBC) is used as an acylating reagent for GC with electron-capture detection (Figure 4). Many of those described above can also react with hydroxyl and phenol groups.
