Step by step solution

01

Formation of acyl chloride

a.Alcohols can be converted to acyl chlorides by treating them with thionyl chloride and pyridine.

The given compound is treated the same way and then further reduced using LiAlH4 .

The product is given below:

Formation of acyl chloride

02

Dihydroxylation using osmium tetroxide

b. When the alkene is reacted with osmium tetroxide and then treated with sodium bisulfite, the product is given below:

Dihydroxylation reaction using osmium tetroxide

03

Epoxidation

c. Treating the alkene with mCPBA leads to the formation of the following epoxide, which is then reduced using LiAlH4 ,H2O . The reaction is shown below:

Epoxidation and reduction of alkene

04

Hydrogenation using Lindlar catalyst

d. The Lindlar catalyst is capable of reducing alkyne to alkene but is unreactive towards alkene.

The reaction is shown below:
