SYNTHESIS OF 5-ALKENYL-2'-DEOXYURIDINES VIA ORGANOSTANNANES
Crisp, Geoffrey T.
, p. 2117 - 2124 (2007/10/02)
The palladium-catalyzed coupling of 3',5'-Di-O-p-toluoyl-5-iodo-2'-deoxyuridine with functionalized and non-functionalized alkenylstannanes gave moderate to good yields of the corresponding 5-alkenyl-2'-deoxyuridines.
