Annulation reaction retrosynthetic analysis

Tran orm-based or long-range strategies The retrosynthetic analysis is directed toward the application of powerful synthesis transforms. Functional groups are introduced into the target compound in order to establish the retion of a certain goal transform (e.g., the transform for the Diels-Alder reaction, Robinson annulation, Birch reduction, halolactonization, etc.). 

How would you synthesize each of the following, using the Robinson annulation Show both your retrosynthetic analysis and a forward reaction scheme, taking care to use enamines, activating and protecting groups as appropriate ... 

A Robinson annulation is comprised of a Michael reaction, followed by an intramolecular aldol condensation. To determine the starting materials necessary to prepare the desired product via a Robinson aimulation, we draw the following retrosynthetic analysis ...
