(a)
Interpretation:
The mechanism of 4-Hydroxybenzaldehyde to compound A has to be shown.
(b)
Interpretation:
The reagent and experiment condition is to be given for the conversion of A to B.
Concept introduction:
(c)
Interpretation:
The mechanism for the conversion of B to C is to be explained.
Concept introduction:
Wittig Reaction: It is an organic reaction where an aldehyde or a ketone gets converted to
(d)
Interpretation:
The reagent and experiment condition is to be given for the conversion of C to D.
Concept introduction:
(e)
Interpretation:
The reagent and experiment condition is to be given for the conversion of D to albuterol.
Concept introduction:
Diol is to protect the ketone and aldehyde (carbonyl group). In this reaction acetone is protected as acetal by using ethylene glycol.
(f)
Interpretation:
The possible stereoisomer’s has to be shown if the product is chiral.
Concept introduction:
Chiral:
A molecule is non superimposable on its mirror image is called chiral molecule. Four different atoms attached to a carbon atom is called chiral molecule.
Isomer: A molecule having the same molecular formula but with different chemical structure is called isomer.
Stereoisomers: Stereoisomers are molecules that have the same molecular formula and they differ only in arrangement of atom in three-dimensional space.
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.
