Matsumura, Noburu,Nishiguchi, Hiroshi,Okada, Masao,Yoneda, Shigeo

, p. 885 - 887 (2007/10/02)

The lithium 1,8-diazabicycloundec-6-ide (1) prepared from 1,8-diazabicycloundec-7-ene (DBU) and n-butyllithium reacts with alkyl halides and carbonyl compounds such as benzophenone, acetophenone, and benzaldehyde to give 6-substituted DBU derivatives in good yields.The reaction behavior of 6-substited DBU was also investigated.
