carboxylic ortho esters could be used as an alkylating agent in the reductivealkylation of amines. A variety of amines, including amino acid esters, were alkylated affording mono‐alkylated products with high selectivity in practical to high yields using standard heterogeneous catalysts. By applying acyclic ortho esters alkylation was completed at room temperature.

Reactions of glucose and ribose with an excess of propylamine in phosphate buffered nearly neutral solution lead to the formation of N-propylalanine propylamide, N-propylglycine propylamide, lactic acid propylamide, and glycolic acid propylamide. The production of these amides is favoured by alkaline conditions. These model reactions represent a new mechanism for cross-linking of proteins, through lysine side chains by sugars.
