Article abstract of DOI:10.3987/COM-93-6560

Methacryloyl isocyanate (MAI) reacted with arylhydrazines (1) to give semicarbazides (2) in good yields.Treatment of 2 with aqueous potassium hydroxide gave the corresponding 1-aryl-3-hydroxy-1,2,4-triazoles (3), whereas thermal ring closure of 2 afforded
