Constrained analogues of 2′-nor cyclic nucleoside monophosphates
摘要:
The synthesis of constrained analogues of 2'-nor-cyclic nucleosides monophosphates containing a thiomethylene tether was readily accomplished from the oxathiolane intermediate 4. The uracil, cytosine, and 5-bromocytosine spirophosphate analogues 22, 16, and 25 were inhibitory to HCMV replication in Flow 2002 cells. (C) 1997 Elsevier Science Ltd.
Syntheses and antiviral activities of 1,3-dioxolanyl-, 1,3-oxathiolanyl- and 1,3-dithiolanylnucleosides with 2-hydroxymethyl substituents
摘要:
Novel 1,3-dioxolanyl-, 1,3-oxathiolanyl- and 1,3-dithiolanylnucleosides with 2-hydroxymethyl substituents (1a-4b) were each synthesized with good yields through the condensation of dinucleophiles (oxygen and/or sulfur) with 1,3-dibenzoxy-2-propanone methyl ketal as a key step.
