Interpretation: The two different methods to carry out the given transformation; a one-step method using a Wittig reaction, and a two-step method using a Grignard reagent are to be stated and the preferred route is to be identified.
Concept introduction: The Wittig reaction is always preferred for the synthesis of

- Procyclidine is a drug that has been used to treat the uncontrolled body movements associated with Parkinson’s disease. Draw three different methods to prepare procyclidine using a Grignard reagent.arrow_forwardWhat Grignard reagent and aldehyde (or ketone) are needed to prepare attached alcohol? Show all possible routes.arrow_forwardExplain why an acetal can be isolated but most hydrates cannot be isolated.arrow_forward
- What Grignard reagent and aldehyde (or ketone) are needed to prepare each alcohol? Show all possible routes.arrow_forwardHow Wittig reagents are synthesized by a two-step procedure ?arrow_forwardEthers are oxidized with O2 to form hydroperoxides that decompose violently when heated. Draw a stepwise mechanism for this reaction.arrow_forward
- Draw compound A and B and identify reagents 1,2 and 3arrow_forwardwhat are the reagents to convert A to Barrow_forwardDraw a stepwise mechanism for the sulfonation of an alkyl benzene such as A to form a substituted benzenesulfonic acid B. Treatment of B with base forms a sodium salt C that can be used as a synthetic detergent to clean away dirtarrow_forward
