  Direct, Regioselective N-Alkylation of 1,3-Azoles

  摘要：

  Regioselective N-alkylation of 1,3-azoles is a valuable transformation. Organomagnesium reagents were discovered to be competent bases to affect regioselective alkylation of various 1,3-azoles. Counterintuitively, substitution selectively occurred at the more sterically hindered nitrogen atom. Numerous examples are provided, on varying 1,3-azole scaffolds, with yields ranging from 25 to 95%.

  A general synthetic approach to 6-guanidinopurines, their ribonucleosides, 2-deoxyribonucleosides, acyclic nucleoside analogues and acyclic nucleoside phosphonates was developed. The approach consists in the reaction of the 6-chloropurine derivatives with guanidine solution in DMF under DABCO catalysis. This method was used to synthesize 6-guanidinopurine and 2-amino-6-guanidinopurine derivatives. Acyclic nucleosides and acyclic nucleoside phosphonates were also obtained by alkylation of the 6-guanidinopurine bases. (C) 2002 Elsevier Science Ltd. All rights reserved.
