Interpretation Introduction

Interpretation:

The suitable reagents for the given transformations in the synthesis of Sabinene from 6-methyl-2,5-heptanedione are to be suggested.

Concept introduction:

The 1,4 carbonyl compound having α-H undergoes intramolecular aldol condensation in the presence of the base like hydroxides gives β-hydroxy ketone which is on dehydration by heating forms cyclic α-β unsaturated ketone.

The ketone on reduction with sodium borohydride forms secondary alcohol.

The conversion of alkene to cyclopropane is carried out by reacting the alkene with iodomethylzinc iodide (ICH2ZnI) in diethyl ether.

Iodomethylzinc iodide (ICH2ZnI) is the organozinc compound prepared by the reaction zinc-copper couple [Zn(Cu)], with diiodomethane (CH2I2) in diethyl ether.

The potassium or sodium dichromate in presence of the strong acid forms chromic acid which is a good oxidizing agent, in hydrous medium oxidizes secondary alcohol to ketone.

The carbon-oxygen double bond can be replaced by carbon-carbon double bond with the help of Wittig reaction using an ylide methylenetriphenylphosphorane.
