The product that is expected from the Robinson annulation reaction of 2-methyl-1, 3-cyclopentanedione with 3-buten-2-one is to be identified. Concept introduction: The Robinson annulations reaction is a two step process that combines a Michael reaction with an intramolecular aldol condensation reaction. In this reaction a nucleophilic donor such as β â€“ ketoester, an enamine or a βâ€“ diketone and an α, β- unsaturated ketone acceptor react to yield substituted cyclic ketones . To identify: The product that is expected from the Robinson annulation reaction of 2-methyl-1, 3-cyclopentanedione with 3-buten-2-one.

Question

Draw the complete structural formula from each condensed structure. Include all hydrogen atoms.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone
