  Synthesis of Hexahydropyrazino[1,2-b]isoquinolines as Simplified Saframycin Analogues

  摘要：

  Various hexahydropyrazino[1,2-b]isoquinolines were synthesised as simplified saframycin analogues. Construction of this core proceeded through a tetrahydroisoquinoline synthesis followed by acylation/alkylation of the tetrahydroisoquinoline nitrogen and subsequent ring closure using various aliphatic and aromatic amines. The resulting piperazinones were reacted with LiAlH4 or LiAlH(OEt)(3) to synthesise further analogues.
