Answer
$OsO_4$ and $H_2O_2$ can be used to synthesize the product.
Work Step by Step
Osmium tetroxide ($OsO_4$, also called osmic acid) reacts with alkenes in a concerted step to form a cyclic osmate ester. Oxidizing agents such as hydrogen peroxide ($H_2O_2$) are used to hydrolyze the osmate ester and add two OH groups across the double bond.
