Robinson annulation:
In the presence of enough bases, the product of the Michael reaction undergoes a spontaneous intramolecular aldol condensation, usually with dehydration to give a six membered ring-a conjugated cyclohexanone.
Reduction can be done using hydrogen (one of the simplest reducing agent) with a metal catalyst.
