A. Arcadi et al., THE PALLADIUM-CATALYZED CARBONYLATIVE COUPLING OF 5-(TRIMETHYLSILYLETHYNYL)-3',5'-DI-O-ACETYL-2' DEOXYURIDINE AND 1-ALKYNES WITH ARYL IODIDES, Synlett, (8), 1995, pp. 823-824
The palladium-catalysed reaction of hylsilylethynyl)-3',5'-di-O-acetyl
-2'-deoxyuridine with aryl iodides in the presence of n-Bu(4)NF and tr
iethylamine under a balloon of carbon monoxide produces (2-acylethynyl
)-3',5'-di-O-acetyl-2'-deoxyuridines in good yields at room temperatur
e. The methodology has been extended to the preparation of alpha,beta-
ynones from 1-alkynes and aryl iodides.
