Ibogaine analogues. Synthesis and preliminary pharmacological evaluation of 7-heteroaryl-2-azabicyclo[2.2.2]oct-7-enes
摘要:
Synthesis of 7-heteroaryl-2-azabicyclo[2.2.2]oct-7-enes by cycloaddition and subsequent cross-coupling reaction is described. Binding affinity of these novel compounds towards the characteristic receptorial targets of ibogaine is illustrated. (C) 2002 Elsevier Science Lid. All rights reserved.
Application of the Pd-catalyzed heteroarylation to the synthesis of 5-(indol-2′-yl)pyridin-2-one and 5-(indol-2′-yl)pyran-2-one
摘要:
The synthesis of 5-(indol-2'-yl)pyridin-2-ones and 5-(indol-2'-yl)pyran-2-one by Pd-catalyzed reactions is described. The best results are obtained using 2-indolylstannanes or 2-indolylzinc halides to be coupled with 5-bromopyridin-2-ones or 5-bromopyran-2-one in the presence of Pd(PPh3)(4) catalyst. Other Pd-catalyzed reactions are discussed. (C) 1998 Elsevier Science Ltd. All rights reserved.
