4971-56-64-羟乙酰乙酸内酯,96%化合物描述
Tetronic acid is a chemical compound, classified as a γ-lactone, with the molecular formula C4H4O3.
It interconverts between keto and enol tautomers. Many natural products such as ascorbic acid (vitamin C), penicillic acid, pulvinic acids, and abyssomicins possess the β-keto-γ-butyrolactone motif of tetronic acid.
In organic synthesis, it is used as a precursor for other substituted and ring-fused furans and butenolides. It is also forms the structural core of a class of pesticides, known as tetronic acid insecticides, which includes spirodiclofen and spiromesifen.
