Synthesis of thieno[3,2-d]pyrimidine-2,4-diones cyclic and acyclic nucleosides as potential anti HIV agents

Jourdan,Laduree,Robba

, p. 305 - 312 (2007/10/02)

Synthesis of cyclic and acyclic nucleosides was achieved by alkylation of 7-methyl or arylthieno[3,2-d]pyrimidine-2,4-diones following the Vorbruggen and Niedballa's method [1]. After a possible deprotection, potential anti HIV agents were obtained.
