scheme or table, p. 3376 - 3378 (2011/06/28)
Synthetic approaches are described for the synthesis of 4-alkoxyindole-7-carboxamides and 4-alkoxy-3-cyanoindole-7-carboxamides, which are useful intermediates in medicinal chemistry research. Two strategies were employed, highlighted by a Bartoli indole synthesis or a sequential and regioselective use of chlorosulfonyl isocyanate to install both the 3-cyano and 7-carboxamido groups. These routes are scalable and afford diversely functionalized indoles for further elaboration.
Synthetic studies towards the 2-aminopyrimidine alkaloids variolins and meridianins from marine origin
Fresneda, Pilar M.,Molina, Pedro,Delgado, Santiago,Bleda, Juan A.
, p. 4777 - 4780 (2007/10/03)
A nine-step synthesis of 9-amino-4-methoxypyrido[3',2':4,5]pyrrolo[1,2- c]pyrimidine, a tricyclic ring system present in the marine alkaloids variolins is described. The natural marine products meridianins C-E have been synthesized for the first time starting from N-protected 3-acylindoles. (C) 2000 Elsevier Science Ltd.
