Abstract:
Due to their numerous reactivity modes, α-aminonitriles represent versatile and valuable building blocks in organic total synthesis. Since their discovery by Adolph Strecker in 1850, this compound class has seen a wide dissemination in synthetic applications from laboratory to million-ton industrial scale and was extensively used in the syntheses of various classes of natural products. As these compounds provide a multitude of reactivity options, we feel that a broad overview of their multiple reaction modes may reveal less familiar opportunities for successful total synthesis planning. This personal account article will thus focus on α-aminonitriles used as key intermediates in selected natural product synthesis sequences which have been reported in the two decades since Enders' and Shilvock's seminal review. Natural α-aminonitriles will also briefly be treated.

Preparation of 1° Amines: Azide Synthesis
Azide ions act as good nucleophiles and react with unhindered alkyl halides to form alkyl azides. Alkyl azides do not participate in further nucleophilic substitution reactions, thereby eliminating the chances of polyalkylated products. Alkyl azides are reduced by hydride-based reducing agents, like lithium aluminum...

Preparation of Amides
The DCC-promoted synthesis of amides begins with the protonation of DCC by carboxylic acid. The protonation makes it a better acceptor. Next, the addition of carboxylate to the protonated carbodiimide gives a reactive acylating agent.
Subsequently, the amine acts as a nucleophile that attacks the acylating agent to form a tetrahedral intermediate. In the...
