The sequence of reagent which can efficiently bring about the above conversion i
The sequence of reagent which can efficiently bring about the above conversion is (are) ? Consider the following synthesis This question has multiple correct options
- A. \( B r_{2} \) -hv/heat
- B. \( B r_{2} \) -hv/heat, \( C_{2} H_{5} O N a / C_{2} H_{5} O H ; N B S- \) \( h v ; B_{2} H_{6}-T H F \) then \( C H_{3} C O O H \)
- C. \( B r_{2} \) -hv/heat \( ;\left(C H_{3}\right)_{3} C O N a-\left(C H_{3}\right)_{3} C O H H B r- \) ROOR
- D. NBS-hv/CCl_
Step-by-step solution
The conversion likely involves multiple steps: allylic bromination with Br2/hv, elimination to form a diene with NaOEt/EtOH, another allylic bromination with NBS/hv, and finally hydroboration-oxidation with B2H6-THF/CH3COOH to add an alcohol. This sequence efficiently achieves the target transformation.
