Chemoselective N-acylation of indoles and oxazolidinones with carbonylazoles
Unique reactivity: In the presence of more reactive amine and alcohol functional groups and of carboxylic acids, the chemoselective N-acylation of indoles (see scheme) and oxazolidinones is achieved by taking advantage of the unique reactivity of carbonylazole acylating agents with catalytic amounts of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU).

A NEW OXIGENATING METHOD USING 1-ALKOXYCARBONYL-1,2,4-TRIAZOLES AND HYDROGEN PEROXIDE RELATIVE REACTIVITY OF O-ALKYLPEROXYCARBONIC ACIDS
A convenient method is reported for the epoxidation of alkenes and the Baeyer-Villiger oxidation of a variety of carbonyl compounds using the 1-alkoxycarbonyl-1,2,4-triazoles (1a-c)/H2O2 system.The reactivities of the resulting peroxycarbonic acids were compared.O-Trichloroethylperoxycarbonic acid prepared in this way was isolated as a chloroform solution and was characterized spectroscopically.KEYWORDS - oxygenation with 1-alkoxycarbonyl-1,2,4-triazole/H2O2 system; peroxycarbonic acid; epoxidation; Baeyer-Villiger reaction
