Interpretation: The structures of 3 and 4 with diastereomeric centers have to be drawn
Concept Introduction:
Sodium cyanoborohydride is a strong reducing agent than sodium borohydride. It reduces the carbonyl group into amine group in a rapid way. So, it is called as reductive amination reactions.
If a carbon is attached with four different groups without any elements of symmetry, then that center has a chirality center. Diastereomers (sometimes called diastereoisomers) are a type of a stereoisomer. Diastereomerism occurs when two or more stereoisomers of a compound have different configurations at one or more stereocenters and are not mirror images of each other. When two diastereoisomers differ from each other at only one stereocenter, they are epimers. Each stereocenter gives rise to two different configurations and thus increases the number of stereoisomers by a factor of two.
To find: Draw the structure of 3 and the reason for its production as a diastereomeric mixture

Interpretation: The structures of 3 and 4 with diastereomeric centers have to be drawn
Concept Introduction:
An amide group is formed from an amine compound and the ester group.
If a carbon is attached with four different groups without any elements of symmetry, then that center has a chirality center. Diastereomers (sometimes called diastereoisomers) are a type of a stereoisomer. Diastereomerism occurs when two or more stereoisomers of a compound have different configurations at one or more stereocenters and are not mirror images of each other. When two diastereoisomers differ from each other at only one stereocenter, they are epimers. Each stereocenter gives rise to two different configurations and thus increases the number of stereoisomers by a factor of two.
To find: Draw the structure of 4 and determine the possibility of its production as a diastereomeric mixture

- Predict the major products of this organic reaction: HBr (1 equiv) Δ ? Some important notes: • Draw the major product, or products, of this reaction in the drawing area below. • You can draw the products in any arrangement you like. • Pay careful attention to the reaction conditions, and only include the major products. • Be sure to use wedge and dash bonds when necessary, for example to distinguish between major products that are enantiomers. • Note that there is only 1 equivalent of HBr reactant, so you need not consider the case of multiple additions.
