Show an arrow pushing mechanism of the synthesis of dimedone from mesityl oxide and dimethyl malonate (Michael addition, cyclization, hydrolysis and decarboxylation)? Heating (1Z,3Z,5Z)-1,3,5-cyclononatriene to 100^\circ C causes cyclization and formation of a bicyclic product. Is the reaction conrotatory or disrotatory?

Michael Addition Reaction: This reaction is named after Arthur Michael, an American chemist who discovered the reaction. It involves the addition of an enolate from a ketone or aldehyde to an {eq}\alpha {/eq}, {eq}\beta {/eq} unsaturated carbonyl.

The Robinson annulation involves two sequential reactions, a Michael addition and an aldol condensation, resulting in the formation of a cyclohexenone derivative. Draw the structure of the two neutral reactants required to form the product below-mentioned.

Robinson annulation is a reaction carried out to afford cyclic α,β-unsaturated carbonyl compounds--usually six-membered rings are formed. The reaction involves (A) Michael addition and (B) aldol condensation. During the Michael addition, a nucleophilic species (e.g. enolate ion) adds to an α,β-unsaturated carbonyl compound.

The Robinson annulation involves two sequential reactions, a Michael addition and an aldol condensation, resulting in the formation of a cyclohexenone derivative. Draw the structure of the two neutral reactants required to form the product below-mentioned; 1. Write the structure of the aldol addition product of 3-methylbutanal. 2.
