The use of Strecker synthesis to make tryptophan and the stereochemistry that is expected in product are to be stated. Concept introduction: The Strecker synthesis involves the synthesis of α − amino acids from the reaction of an aldehyde with hydrogen cyanide and ammonia. This reaction yields α − amino nitrile as an intermediate. The hydrolysis of α − amino nitrile (an intermediate) yields D and L form of α − amino acids.

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
