  Synthesis of Pyridopyrazine-1,6-diones from 6-Hydroxypicolinic Acids via a One-Pot Coupling/Cyclization Reaction

  摘要：

  A facile one-pot synthesis of 3,4-dihydro-1H-pyrido[1,2-a]pyrazine-1,6(2H)-diones (pyridopyrazine-1,6-diones) has been developed which employs a sequential coupling/cyclization reaction of 6-hydroxypicolinic acids and beta-hydroxylamines. The transformation proceeds In good yield under mild conditions using O-(7-aza-1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (HATU) to both carry out the amide formation and activate the hydroxyl group for intramolecular alkylation.

  utility, this novel reaction has been used to prepare a series of acyclic nucleoside-like compounds. Because BtO(-) is a nucleofuge, several Bt-OCH2Ar substrates have been evaluated in nucleophilic substitution reactions. Finally, the possible formation of Pd pi-allyl complexes by departure of BtO(-) has been queried. Thus, alpha-allylation of three cyclic ketones was evaluated with 1-(cinnamyloxy)-1H-benzo[d][1
