Unusual methylene transfer in reactions of Simmons-Smith reagent with 1,3-diazabuta-1,3-dienes: synthesis of functionalised imidazole derivatives
The reactions of Simmons-Smith reagent with 1-aryl-2-phenyl-4-methylthio-4-secondary amino 1,3-diazabuta-1,3-dienes 1 underwent an unusual 1,4-methylene transfer resulting in the formation of 1-aryl-2-phenyl-4-secondary amino imidazoles 4. Whereas, its reactions with 1-aryl-2-phenyl-4-secondary amino-1,3-diazabuta-1,3-dienes 8 underwent an initial 1,2-methylene transfer leading to an aziridine intermediate which rearranges to 1-aryl-4-phenyl-imidazoles 11.
