摘要：

Proteinogenic amino acids were sublimed in gram quantities in the presence of silica. High-performance liquid chromatographic and fast-atom-bombardment mass-spectrometric measurements showed that diketopiperazines (DKPs) were the main products of silica catalyzed thermal transformations in the case of aliphatic bifunctional amino acids. Intensive formation of products of decarboxylation, deamination and some other reactions was observed in the cases of trifunctional amino acids and phenylalanine. Possible mechanisms of reactions occured have been discussed. Principal possibility of 'gas-solid-phase' DKP synthesis has been demonstrated for bifunctional aliphatic amino acids.
