Tetrazoles. 33. New method for obtaining functionally substituted tetrazoles
The interaction of 5-methylsulfonyl-1-phenyltetrazole with C-, N-, and O-nucleophiles at 18–20°C gives high yields of 1-phenyltetrazoles that are functionally substituted on the carbon atom of the heteroring. Prospects are examined for the use of 5-methylsulfonyl-1-phenyltetrazole as a universal synthon in the synthesis of tetrazoles with various types of structure.
