Q.29. - Organic Chemistry

Question

Question: What steps are needed to convert A to B?

Step-by-Step Solution

Answer

Answer

Step 1: Ozonolysis

${\mathit{O}}_{\mathbf{3}}$ in the presence of  ${\left(C{H}_3\right)}_{\mathbf{2}}\mathit{S}$  introduces double-bonded oxygen at each of the carbon in the C=C bond.

Step 2: Intra-molecular aldol reaction

In acyclic compounds containing two carbonyl groups, the aldol reaction may help to form either a five or a six-membered ring.

Step 3: Steps of the given reaction

The above-given reaction proceeds via two reactions. Both of these steps are shown here under.
