1-Phenyl-3-oxabicyclo[3.1.0]hexan-2-one (1POX) is a monomer that belongs to the class of cyclopropane compounds and can be used in the synthesis of polymers. It has been shown to react with benzene, irradiation, monoxide, oxiranyl, acetonitrile and trimeric dyes to form reactive intermediates such as ketones and carboxylic acids. These intermediates can undergo photolysis to produce products such as ketones and carboxylic acids. The wavelength of the light used for photolysis can influence the product formation. 1POX is also a substrate for cyclopropane ring formation reactions, which are known for their high reactivity due to the stability of this ring system. The carbonyl group on 1POX is electron withdrawing and stabilizes the planar geometry of 1POX.

3-Methyl-2-pyridone is an intermediate in the biosynthesis of pyridine nucleotides. It is activated by intramolecular hydrogen and water molecule, which are released during the enzymatic decarboxylation of 3-methyl-2-pyridone to form a reactive imine group. This group then reacts with a carboxylic acid group to form an amide. 3-Methyl-2-pyridone also has a hydrophobic tail that stabilizes the enzyme complex by reducing Coulombic repulsion. The genetic factors that influence the activity of this enzyme include polymorphisms in the gene encoding for HADH and HMGCS1, as well as mutations in the gene encoding for SLC25A1.
