|Title:||Solution-phase parallel synthesis of S-DABO analogues||Authors:||Togninelli, Andrea
|Issue Date:||2006||Project:||None||Journal:||TETRAHEDRON LETTERS||Abstract:||
A simple and straightforward methodology for the parallel, solution-phase synthesis of a new series of S-DABO derivatives 1 and 2, bearing aromatic substituents at the C2 and C6 positions, has been developed. Starting from potassium ethyl malonates 3, thiouracil intermediates 5 were prepared through parallel synthesis and isolated as pure products by simple extraction with ethyl acetate. Selective S-benzylation of 5 was achieved in few minutes under microwave irradiation to give the title compounds 1, which were oxidized in parallel to the corresponding sulfones 2. Some of the new compounds 1 showed potent inhibitory activity against HIV-1 RT.
