hydrazine, followed by chlorination with POCl3. We have also discovered twonovel transformations of 3-vinyl- and 3-alkynyl-3-hydroxyisoindolinones. Addition of vinyl organometallic reagents to N,N-dimethylaminophthalimide (8a) provided dihydrobenzoazepinediones 15a–15c via the proposed ringexpansion of 3-vinyl-3-hydroxyisoindolinone intermediates. 3-Alkynyl-3-hydroxyisoindolinones react with hydrazine and

The present application provides novel cephem, penem, and monobactam compounds that exhibit antibiotic activity against both Gram-negative and Gram-positive bacteria, as well as compositions comprising these compounds and methods of using these compounds and compositions to treat bacterial infections.
copper-catalyzed sequential cyclization/migration reaction of alkynyl hydrazides for the synthesis of ring-expanded N–N fused pyrazolones was developed. Control experiments indicate that the copper–ligand complex plays an essential role in the reaction. This approach features a broad scope including some functionalgroup tolerance as well as a nucleophilic addition/1,3-migration/formal 1,2-migration sequence. This
