Photolysis of 2-alkyl-2-azido-3-oxobutanoic esters and amides gave products resulting from alkyl or acyl migration onto nitrogen.The resulting ketimines could be isolated in moderate purity, but the N-acyl imines were rapidly converted into solvation products or enamides (N-acylated dehydroamino acid esters) resulting from double bond migration.Mechanisms for formation of these products are discussed.The N-(2-azido-2-methyl-3-oxobutanoyl) derivative of the diketopiperazine from L-valyl-L-proline gave a stereoisomer of the cyclol tripeptide unit of ergovaline.
