A Novel Synthesis of 1-OXA-HPMPA: A Potent Antiviral Agent Against Herpesviruses
Kim, Choung Un,Luh, Bing Y.,Martin, John C.
, p. 25 - 28 (2007/10/02)
A facile synthesis of 1-oxa-HPMPA 2 was achieved via a novel strategy of coupling 9-hydroxyadenine 13 and enol ether phosphonate 11.The newly synthesized 1-oxa analogue of HPMPA exhibited potent antiherpesvirus activity. Key words: HPMPA; 1-oxa-HPMPA; her
