Abstract:
Pyrazole moiety is considered as an important N-heterocycle in pharmaceuticals and many other functional molecules. The utilization of multicomponent reaction is a major tool in the current approaches of pyrazole synthesis. Considering the power and significance of multicomponent pyrazole synthesis, we review herein the latest developments in this field. According to the typical features, the contents are divided into reactions with different NN fragment sources, such as hydrazine, hydrazone, amidine, nitrile, and diazo compounds, in the pyrazole ring construction, covering the works published since 2019 to date.

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...
