The Stork en amine reaction and the intra molecular aldol reaction can be carried out in sequence

Question:

The Stork en amine reaction and the intra molecular aldol reaction can be carried out in sequence to allow the synthesis of Cyclohexanone. For example, reaction of the pyrrolidine enamine of Cyclohexanone with 3-huten-2-one, followed by enamine hydrolysis and base treatment, yields the product indicated. Write each step, and show the mechanism ofeach.
