An unusual decarboxylative Maillard reaction between L-DOPA and D-glucose under biomimetic conditions: factors governing competition with Pictet-Spengler condensation

Research has been conducted on the reaction of L-3,4-dihydroxyphenylalanine and dopamine with D-glucose. The nature of the competing pathways, the role of the transition metal cations and the chemical viability of the nonenzymatic glycation processes have been investigated.
