2-(4-Penten-1-yl)-1H-isoindole-1,3(2H)-dione is an intermediate in synthesizing 4-Penten-1-amine (P227400), which in the presence of sugars, lysine, similarly to asparagine and phenylalanine, can undergo carbonyl-assisted decarboxylative deamination reaction to generate pent-4-en-1-amine, the counterpart of acrylamide.
