Influence of the N3-protection group on N1- vs. O2-alkylation in the Mitsunobu reaction
Ludek, Olaf R.,Meier, Chris
, p. 941 - 946 (2006)
The influence of the N3-protection group of thymine on the regioselectivity of the N1- vs. O2-alkylation under Mitsunobu conditions is described. A series of N3-protected thymine derivatives 8a-f was prepared and coupled to cyclopentanol as mod
