Aza-analogues of ganciclovir have been prepared via coupling of nucleobases with N-[2-pivaloyloxy-1-(pivaloyloxymethyl)ethyl] methanesulfonamide or 3-mesyl-4-(benzoyloxymethyl)-1,3-oxazolidine. (c) 2006 Elsevier Ltd. All rights reserved.
Facile synthesis of acyclic azanucleosides from N -pivaloyloxymethyl amides and sulfonamides: synthesis of aza-analogues of Ganciclovir
摘要:
N-Pivaloyloxymethyl amides and sulfonamides, readily available from N-alkylation of both amides and sulfonamides with commercial chloromethyl pivaloate, were converted into acyclic azanucleosides via a one-pot base silylation/nucleoside coupling procedure. (C) 2004 Elsevier Ltd. All rights reserved.
