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...

1. The reaction web includes most of the reactions of enolates we have studied. The products of these reactions can be treated with other reagents to generate new functionality - think synthesis! Make up your own examples - e.g. What if you treated compound D with CH,MgBr? In the table, summarize the types of products produced from these reactions. CH3 MgBr acid quench acid quench NaOH, H2O EIO OEt acid quench acid quench acid quench D LIAIHA acid quench acid...
