Synthesis of a new bridged diamine 3,6-diazabicyclo [3.2.0] heptane: Applications to the synthesis of quinolone antibacterials
Jacquet,Bouzard,Kiechel,Remuzon
, p. 1565 - 1568 (2007/10/02)
Diprotected 3,6-diazabicyclo [3.2.0] heptane has been prepared by an highly efficient process. Selective deprotection, followed by condensation with 7-halogenoquinolones led to the naphthyridones 10 and 13 and the quinolone 14.
