Vedclass · Answer

(D) The reaction is a hydroboration-oxidation of $1$-Methylcyclopentene using deuterated reagents. $1$. The first step involves the addition of $B-D$ across the double bond via syn-addition. The boron atom attaches to the less substituted carbon,and the deuterium atom attaches to the more substituted carbon. $2$. The second step is the oxidation with $D_2O_2$ in the presence of $NaOD$,which replaces the boron group with an $-OD$ group with retention of configuration. This results in the anti-Markovnikov addition of $D$ and $OD$ across the double bond with syn-stereochemistry. Therefore,the correct reagent is $1. B_2D_6, 2. D_2O_2, NaOD$.

Which of the following reagents can be used for the conversion of $1$-Methylcyclopentene to the given product?
