The palladium-catalysed reaction of 5-(trimethylsilylethynyl)-3',5'-di-O-acetyl-2'-deoxyuridine with aryl iodides in the presence of n-Bu4NF 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 α,β-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-Bu4NF 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 α,β-ynones from 1-alkynes and aryl iodides.File in questo prodotto:
