Synthesis of 1,2,3,4,5,6-Hexahydropyrrolo[3,4-c]pyrrole Dihydrobromide and 1,2,3,5-Tetrahydro-2-[(4-methylphenyl)sulfonyl]pyrrolo[3,4-c]pyrrole
摘要:
Synthesis of the pyrrolo[3,4-c] pyrrole derivatives (8) and (9) is reported. Nucleophilic aromatic substitution of the 7-fluoride of 1-cyclopropyl-6,7,8-trifluoro-1,4-dihydro-4-oxoquinoline-3-carboxylic acid (1) by 8 under basic conditions followed by N-methylation, gives the quinolone antibacterial agent (11) (KR 10755, HK 3140).
