The major products X and Y formed in the following reaction sequences are
The reaction sequence involves a two-step transformation of the starting compound to form the major products X and Y.
Step 1: Transformation to Product X
- The starting compound undergoes hydroboration-oxidation. Thexylo borane (Thexylborane) is used for hydroboration.
- Hydroboration-oxidation adds water across the double bond of the alkene, with the OH group attaching to the less substituted carbon due to anti-Markovnikov addition.
- The reaction with carbon monoxide and water produces a carboxylic acid. This step is followed by oxidation using sodium acetate (NaOAc) and hydrogen peroxide (H2O2), resulting in further formation of a carboxylic acid derivative.
Step 2: Conversion to Product Y
- Lithium diisopropylamide (LDA) with trimethylsilyl chloride (TMSCl) facilitates enolate formation. The enolate reacts further under the influence of additional reagents.
- The further treatment with phenylsulfenyl chloride (PhSCl), meta-chloroperoxybenzoic acid (m-CPBA), and subsequent heating results in the formation of an epoxide and then a rearrangement to form a ketone.
This sequence leads to specific transformations that result in the final major product Y.
Conclusion: The major products X and Y formed during the reaction sequence are determined by these transformations, leading to the correct evaluation of the given options.
