To draw the structures from A to I in following synthesis scheme. Concept introduction: In nucleophilic aromatic substitution reaction, the nucleophile is substituted on the benzene ring by displacing a good leaving group. FeBr 3 does bromination of benzene gives product A. In the presence of Grignard reagent product B is formed. The epoxide ring opens to form alcohol C. Oxidized to D. After transformation gives acid chloride E. which undergoes Friedel-Crafts acylation to form ketone F, after reduction gives G which undergoes dehydration to form H. The alkene H then undergoes diels-Alder reaction to form I. NaBH 4 is a reducing reagent and capable of reducing aldehyde or ketone to primary and secondary alcohol respectively.

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.
