1. A Robinson annulation is a reaction that involves: (i) a Michael addition of an enolate onto an ,ß-unsaturated enone followed by (ii) an intramolecular aldol reaction. The molecule shown below (cyclohexenone X) can be made through two different Robinson annulation reactions. (A) Show the two different sets of starting materials (i.e. ketone 1 &a,p-unsaturated enone 1 and ketone 2 & a,B-unsaturated enone 2) for each Robinson annulation. Draw the reagents/reaction conditions. (B) Then pick one set and draw an...

The Robinson annulation is a classic example of what could be considered a paired reaction - that is a reaction that is made up of a sequence of two simpler reactions. In the case of the Robinson annulation, it is a Michael Addition followed by an intramolecular aldol. For the following Robinson annulation, go through the mechanism of the initial Michael addition and then look at how many different intramolecular aldol reactions could...
