摘要

Preparation via the Heck reaction of 5-(E)-(3-trifluoroacetamidoallyl)-2′-deoxycytidine (3a) and some N4-formamidine protected derivatives is reported. Difficulties with coupling N-allyl- trifluoroacetamide to 5-iodo-2′-deoxycytidine were overcome by using Pd2 (dba) 3 as catalyst and temporary dimethylformamidine protection of the N4-amine of the nucleoside. Compound 3a was isolated with 60% overall yield by crystallization.
