【The invention's effect】
The present invention is a simple method for producing an enol ether derivative. The enol ether derivative obtained by the present invention can be converted to a 1,2-dioxetane derivative capable of chemiluminescence by reacting with singlet oxygen. The 1,2-dioxetane derivative is excellent in thermal stability, has a short time until the light emission amount per unit time reaches the maximum value after the start of light emission, and has a characteristic that the maximum light emission amount is high. It is easy to apply to high sensitivity analysis system. Furthermore, the molecular design is made so that it can be easily bound to an amino acid or a peptide, and it can be easily applied to a label.
