please complete number 1 and 2 COMPLETELY
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...
