How the given set of compounds can be prepared starting from diethyl malonate and other reagents Concept introduction: When a diketone is deprotonated to form a doubly stabilized enolate ion (Michael donor) which acts as a nucleophile for 1,4-conjugate addition to α , β -unsaturated compound (Michael acceptor) is known as Michael reaction. Michael reaction is thermodynamically controlled. A general scheme is shown below,

Next, record any regiochemistry or stereochemistry considerations relevant to the reaction. You should also record any key aspects of the mechanism, such as forma- tion of an important intermediate, as a helpful reminder. You may want to keep track of all reactions that make carbon-carbon bonds, because these help you build large molecules from smaller fragments. This especially applies to the reactions in…
