Concept introduction:
Oxime formation:
(c)
Interpretation:
The reductive amination is to be explained and the explanation has to be given for two step synthesis of amination is used rather than reductive amination.
Concept introduction:
Reductive amination reaction: Amination is the process by which an
The conversion of Carbonyl group in to amine via imine intermediate is called reductive amination.
(D)
Interpretation:
The reagent and condition is to be proposed for step 4 and step 5.
Concept introduction:
Reduction: Aldehydes or ketones undergoing reduction by using reducing agent like LAH or NaBH4 which provides alcohol.
(E)
Interpretation:
The possible stereoisomer’s has to be shown if the product is chiral.
Concept introduction:
Isomer: A molecule having the same molecular formula but with different chemical structure is called isomer.
Enantiomers: A compound which is non-superimposable mirror image is called enantiomers.
Diastereomers: A compound which is non-superimposable and non-mirror image is called diastereomers.
Racemic mixture: A racemic mixture is simply a mixture containing an equal amount of each enantiomer.
Achiral:
A molecule is superimposable on its mirror image is called achiral molecule.
