Deoxyarbutin is synthesized by deacetylation of 2-[(4-acetyloxy)]tetrahydropyran, with the sodium borate, which is an intermediate obtained by condensation of 3,4-dihydropyran and monoacetyhydroquinone. Meanwhile, optimisations have been made with yields of 83.4%, 83.9% and 80.4% for each step , and a total yield of 56.3%, which is about 2.5 times of previous result. The procedure of the recent route is performed easily at room temperature, under the presence of common salts（sodium hydrogen sulfate，PPTs,and sodium borate for each step） used as catalysts.
