  Intramolecular Cyclization of δ-Iminoacetylenes:  A New Entry to Pyrazino[1,2-a]indoles

  摘要：

  The synthesis of the pyrazino[1,2-alpha]indole nucleus was achieved by intramolecular cyclization of several 2-carbonyl-1-propargylindoles in the presence of ammonia. The reaction conditions were optimized using microwave heating and a pool of catalysts. Cyclization of 1-alkynylindole-2-carbaldehydes was easily accomplished under standard heating conditions, whereas microwave heating contributed to reduced reaction times and improved overall yields. Moreover, a fine-tuning of the microwave irradiation time made possible the selective synthesis of both pyrazino[1,2-alpha]indole isomers. TiCl4 proved the catalytic system of choice to achieve pyrazinoindoles in satisfactory yields starting from 1-alkynyl-2-acetylindoles and 1-alkynyl-2-benzoylindole derivatives. Also in these cases, microwave heating contributed to faster reactions and improved yields. The uncatalyzed versus catalyzed reaction mechanism is discussed.

  黄金催化的肟-肟重排

  摘要：

  研究了具有炔丙基连接到氮原子上的吡咯和吲哚肟的金催化反应。在金催化剂的存在下，对于末端炔烃观察到环化的选择性6 -endo-dig模式，引起吡嗪N-氧化物的形成。然而，与取代炔烃的反应通过7-内-挖-环化过程将肟官能团从一个碳原子分子内转移到另一个碳原子上。这种转变在文献中是空前的，被称为肟－肟重排。

  domino synthesis of pyrrolopiperazine fused with oxazine/imidazole by the reaction of pyrrole-derived δ-alkynyl aldehydes and nucleophilic amines was performed. This domino strategy involves the formation of two new C–N bonds and one C–O/C–N bond, resulting in the formation of two new interesting fused heterocycles. Some of the synthesized compounds exhibit promising growth inhibitory activity against

  Indole‐tethered amino allenynes were chemodivergently cyclized for the controlled preparation of fused polycyclic indoles using gold catalysis. Double cyclization of terminal allenynes afforded hexacyclic 15 H‐indolo[1,2,3‐de]quinolino[3,2,1‐ij]quinoxalines, in which allenynes bearing a substituted alkyne at the terminal end generated 12,13‐dihydro‐7 H‐indolo[3,2‐c]acridines, which are 5‐membered cyclized

  The unusual [1,4]oxazino[4,3-a]indole nucleus was prepared, under mild reaction conditions, by reacting 1-alkynyl-1H-indole-2-carbaldehydes with various alkoxides, generated in situ from the corresponding alkyl, benzyl, allyl and propargyl alcohols. (c) 2005 Elsevier Ltd. All rights reserved.
