Interpretation Introduction

Interpretation:

The given reagents used to accomplish the target products (major product) transformation should be draw and identified.

Concept introduction:

Wittig reaction: This process allows the preparation of an alkene by the reaction of an aldehyde $\left(\text{-CHO}\right)$ or ketone $\left(\text{-C=O}\right)$ with ylides generated from a phosphonium salt. The geometry of the resulting cis, trans alkene depends on the reactivity of the ylide.

Nucleophilic Substitution reaction: electron rich nucleophiles attack the positive or partially positive charge of an atom and replace a leaving group is called Nucleophilic Substitution reaction.

Hydrolysis Reaction: This type of reaction involving the braking of a carbon-carbon triple, double bonds in a molecules using water.

Meta-chloroperoxybenzoic acid (m-CPBA): This reagent is extremely useful reagent most frequently encountered in the synthesis of epoxides when added to alkenes or alkynes.

LAH Reduction: The saturated/unsaturated aldehyde and ketones in the presence of sodium metal in LAH and carbonyl compound produced saturated alcohols. The keto group involves in the reduction process of LAH, this end up reducing to give the alcohols.

Oxidation Reaction: The oxidation-reduction reaction is a type of chemical reaction it is involves a transfer of electrons between two species. In other words oxidation reaction number of a molecule atom or ion changes by gaining or losing electrons.

Grignard Reaction: This is a organometallic reaction in different alkyl, aryl-magnesium halides add to a carbonyl group in an aldehyde and ketone. This reaction is an important for the conversion of carbon-carbon single (-C-C-) bond. Moreover the addition of a reagent to an aster, lactone gives a tertiary alcohol in which wo alkyl groups are the same and the addition of a Grignard reagent to a nitrile produces an unsymmetrical ketone.

To identify: The given synthetic route to accomplish the target molecule transformation.
