Synthesis of C-4 substituted pyrimidine nucleoside analogs. Preparation of several 4-(2-oxoalkylidene)-2(1H)-pyrimidinone ribonucleosides

Acevedo,Andrews,Dunkel,Dan Cook

, p. 989 - 995 (2007/10/02)

A series of 4-(1-alkynyl)-2(1H)-pyrimidinone ribonucleosides were synthesized from the Pd-catalyzed coupling of terminal alkynes to the 4-chloropyrimidin-2-one ribonucleoside (2). These compounds were hydrated, using three different methods, to afford the
