2. Consider the following esters. (a) Two of these esters are converted to B-keto esters in good yield on treatment with sodium ethoxide and subsequent acidification of the reaction mixture. Which two? Write the structure of the Claisen condensation product for each one. (2) (b) One ester is capable of being converted to a B-keto ester on treatment with sodium ethoxide, but the amount of B-keto ester that can be isolated after acidification of the reaction mixture is quite small....

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...

Write an equation for the Aldol reaction that takes place for the aldehyde you used for this experiment. Show the exact structures for aldehyde and product (not "general" structures with "R" groups). 1 2 Compare the crude and purified melting points from this lab with the literature melting point of your compound. What do these data say about the purity of your "green chalcone before and after purification? 14 When only a...
