Concept introduction:
During epoxidation an oxygen atom is transferred to the double bond in alkene with syn stereochemistry. Both C-O bonds are formed o the same face of the double bond. The
The hydroxylation with OsO4 also occurs with syn stereochemistry. The addition of OsO4 to the alkene gives a cyclic osmate which is cleaved by using aqueous NaHSO3 to yield a cis-1,2-diol.
To state:
The alkene from which the alcohol shown can be prepared. Further to state, among epoxide hydrolysis and OsO4, the method which can be used to prepare the diol.
