Azide synthesis method facilitates synthesis of organonitrogen compounds

A team of researchers led by Associate Professor Suguru Yoshida from Tokyo University of Science (TUS) in Japan has made a significant breakthrough in azide synthesis, a crucial step in the production of amines and triazoles used in organic and materials chemistry.

Their recent article published in the journal Frontiers in Chemistry details an innovative and efficient method to prepare organomagnesium intermediates containing a protected azido group. The researchers protected the azido groups using di(tert-butyl)(4-(dimethylamino) phenylphosphine (Amphos) and performed an iodine-magnesium exchange reaction, resulting in the preparation of diverse azides through transformations with various electrophiles, followed by deprotection with elemental sulfur.

This novel synthesis method, based on the Grignard reaction, proved highly effective in creating a wide range of azide compounds. Given the central role of azide compounds in the synthesis of 1,2,3-triazoles in click chemistry, this development is expected to significantly contribute to the efficient production of pharmaceuticals and other industrially important products.

Associate Professor Suguru Yoshida expresses optimism about their ongoing research on the preparation and transformation of carbanions with phosphazide moieties, which aims to expand the potential applications of these compounds. The seamless and efficient synthesis of azides will have a profound impact on synthetic organic chemistry, pharmaceutical sciences, and materials chemistry communities, enabling the synthesis of diverse organonitrogen compounds and benefiting various industries.
