Question

Question: Predict the products of these reaction sequences.

a.

Short answer

Answer

Step-by-step solution

Reaction with LDA

LDA is the lithium di-isopropylamide (C₄H₉Li )it is the strong base used to protonate the acidic hydrogen to form lithium enolate.

Alkylation of the enolate ion

In reaction with the LDA formation of lithium, enolate occurs followed by the reaction of alkyl halide formation of the alkylated product occur.

Formation of the product

After the reaction with LDA formation of anionic species take place. Then finally removal of halogen takes place allylic halide. And the substitution of allyl halide takes place.

The formation of the product is as follows:
