Question
Chapter 25, Problem 31P
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
The ketone on reduction with sodium borohydride forms secondary alcohol.
The conversion of
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.
