The palladium-catalysed reaction of 5(trimethylsilylethynyl)-3',5'-di-O-acetyl-2'-deoxyuridine with aryl iodides in the presence of n-Bu(4)NF and triethylamine under a balloon of carbon monoxide produces 5-(2-acylethynyl)-3',5'-di-O-acetyl-2'-deoxyuridines in good yields at room temperature. The methodology has been extended to the preparation of alpha,beta-ynones from 1-alkynes and aryl iodides.

Abstract

The palladium-catalysed reaction of 5(trimethylsilylethynyl)-3',5'-di-O-acetyl-2'-deoxyuridine with aryl iodides in the presence of n-Bu(4)NF and triethylamine under a balloon of carbon monoxide produces 5-(2-acylethynyl)-3',5'-di-O-acetyl-2'-deoxyuridines in good yields at room temperature. The methodology has been extended to the preparation of alpha,beta-ynones from 1-alkynes and aryl iodides.
