A convenient and efficient protocol has been developed for the synthesis of thiocyanated aminonitroalkenes and 2,4,5-trisubstituted thiazoles/selenazoles from β-aminonitroalkenes and N‑thio/selenocyanatosaccharin. This method features simple operation, mild reaction conditions, short reaction time, good functional group compatibility and metal-free characteristics. The broad applications of polysubstituted thiazoles/selenazoles in organic and medicinal chemistry make this protocol much more practical.

A facile and efficient protocol has been developed for the synthesis of (methylsulfanyl)indolizine derivatives via oxidative [3+2]‐annulation of bis(methylthio)‐2‐nitroethylen(BMTNE) and pyridinium ylides under K2CO3. The target products could be obtained in moderate to good yields.
