Abstract


Novel water-soluble sulfonyl azides were synthesized, which are basic by nature. The obtained compounds were used as donors of the diazo group in the diazo transfer reaction. Due to their good solubility in water and high polarity, the byproducts formed in this case were easily separated from the desired products by washing with water or column chromatography. It was also shown that new sulfonyl azides as a result of reactions can be incorporated in heterocyclic products, imparting them water solubility.

Keywords


sulfonamides; sulfonyl azides; 1,2,3-thiadiazoles; 1,2,3-triazoles; diazo transfer reaction; Regitz reaction.
