Question

A chiral amine A having the R configuration undergoes Hofmann elimination to form an alkene B as the major product. B is oxidatively cleaved with ozone, followed by $C{H}_{3}SC{H}_3$ , to form $C{H}_2=O$ and$C{H}_{3}C{H}_{2}C{H}_{2}CHO$ .What are the structures of A and B?

Short answer

It involves the oxidative cleavage of a double bond in alkene in the presence of ozone followed by the reducing agent.

Step-by-step solution

Ozonolysis 

It involves the oxidative cleavage of a double bond in alkene in the presence of ozone followed by the reducing agent.
