Answer
The product can be synthesized using $Br_2$ and $H_2O$.
Work Step by Step
$Br_2$ and $H_2O$ adds a bromine and an OH across the double bond. First one Br adds across the double bond and forms the bromonium ion. The bridge formed blocks one surface. Then the water has to attack from the other side, giving trans addition of OH. There is also a formation of enantiomers.
