Abstract
The present invention relates to a method of preparing an asymmetric phosphate-based compound. According to the method of the present invention, since a thiolane-based cyclic compound is used alone in a hydrophobic solvent under a base-free condition, the yield of a desired compound may be increased due to excellent reaction stability and reduced side reactions.
