How will you convery 3-oxocylohexane carbaldehyde into -3 hydroxy-3- methyl cyclohexanecarbaldehyde? |
Answer» Solution : Aldehydes are more reactigve as compared to ketones. In a compound containing both aldehyde and keto group, the reaction occures at -CHO group preferntially. So in these transformation selective protection of -CHO group is carried out through acetal formation. The finally DEPROTECTION of -CHO with ethylene glycol is DONE with catlytic amount of ACID. The reactions are then carried out selectively at keto group and finally deprotection of -CHO group is done through acidic hydrolysis.
