title: Preparation of 1-(3-C-(propa-1,2-dienyl)-D-ribo-pentofuranosyl)uracil, an allenic nucleoside.
abstract: The Crabbé reaction was extended to the preparation of C-3'-allenyl-uridine. The effects of solvent and protecting group on the reaction were studied. The conversion in refluxing dioxan of disilyl either 3 proceeds to the corresponding allenic nucleoside 7; whereas, in refluxing THF the Mannich base 5 was obtained. Fully deprotected Mannich base and allenic uridines 6 and 9 were tested for their antitumor activity.
