Chapter 19, Problem 19.41P

Interpretation Introduction

Interpretation:

The mechanism for an enamine based conversion has to be proposed.

Concept Introduction:

Enamine reaction:

An enamine, the nitrogen is $s{p}^2$ hybridisation, so there is overlap of the $2p$ orbital of nitrogen atom with the $2p$ orbitals of the carbon-carbon double bond. This overlap allows electrons delocalization and thus stabilization of the enamine.
