(a)
Interpretation: Synthesis for given compound using starting material has to be written.
Concept introduction: Synthesis of final compound is done using given starting material. Starting material is treated with a base. The enolate ion attacks on ethyl bromide to give the final product. The reaction between enolate ion and alkyl bromide is
(b)
Interpretation: Synthesis for given compound using starting material has to be written.
Concept introduction: Synthesis of final compound is done using given starting material. Starting material is treated with base and a cyclic species is formed. Intermediate species is treated with alkoxide base and ethyl bromide. In next step hydrolysis and decarboxylation takes place and the final product is obtained.
(c)
Interpretation: Synthesis for given compound using starting material is to be written.
Concept introduction: Synthesis of final compound is done using given starting material. Starting material have no
(d)
Interpretation: Synthesis for given compound using starting material has to be written.
Concept introduction: Synthesis of final compound is done using given starting materials. Starting material is treated with alkoxide base and cyclopentyl bromide. In the next two steps decarboxylation takes place and the final product is formed.

- Fluorination of a benzene ring can be accomplished with Selectfluor, a reagent that contains a fluorine bonded to a positively charged nitrogen atom. Fluorination is a useful reaction because several common drugs, such as the cholesterol-lowering drug atorvastatin, contain a fluorine bonded to an aromatic ring. Assuming that fluorination is analogous to other examples of electrophilic aromatic substitution, draw a stepwise mechanism for the following reaction.arrow_forwardPropose a synthesis for each of the following compounds using benzene as the starting material.arrow_forwardIdentify the best reagents to complete the following reaction.
