  Nucleoside sultones: synthons for the preparation of novel nucleotide analogs. 1. Synthesis and ring-opening reactions

  摘要：

  Treatment of either the 5'-O-tosyl or the 5'-O-mesyl derivative of 3'-O-mesylthymidine with lithium acetylide-ethylenediamine complex in DMSO affords the intramolecular 6,3-ester of 1,2,5,6-tetradeoxy-l-(3,4-dihydro-5-methyl-2, 4-dioxo-1(2H)-pyrimidinyl)-beta-D-erythro-hexofuranuronosulfonic acid (2). Similarly, the 5'-O-tosyl or 5'-O-mesyl derivative of 1-(2-deoxy-3-O-mesyl-beta-D-threo-pentofuranosyl)thymine affords the intramolecular 6,3-ester of 1,2,5,6-tetradeoxy-1-(3,4-dihydro-5-methyl-2,4-dioxo-1(2H)-pyrimidinyl)-beta-D-threo-hexofuranurononsulfonic acid (5). Sultone 5 reacts with a variety of nucleophiles to afford good yields of the corresponding 3'-substituted sulfonate salts (6, 7, 9, and 10) and, in some cases, the unsaturated nucleoside 8. Sultone 2 was generally much less susceptible to ring opening by nucleophiles. However, in the presence of base, nucleophilic substitution with azide ion did proceed via the intermediate anhydronucleoside, 11, to afford 6. Reaction of 2 with EtOH-NaOH afforded a 1:1 mixture of the epimeric 3'-hydroxy compounds 9 and 12. The above sulfonate salts represent interesting new isosteres of nucleoside 5'-O-phosphates.

  摘要：

  A mild, efficient and inexpensive detritylation method is reported that uses trifluoroacetic acid on a silica gel column to obtain pure, detritylated compounds in one-step. This method is applicable to acid stable as well as acid sensitive compounds with only slight alterations in the procedure. Nineteen examples are given. (C) 2001 Elsevier Science Ltd.

  A series of base-modified pyrimidine 3'-azido-2',3'-dideoxynucleosides and 3'-substituted purine and pyrimidine 2',3'-dideoxynucleosides have been synthesized and evaluated for their inhibitory activity against human immunodeficiency virus (HIV) replication in MT-4 cells. The following pyrimidine derivatives emerged as the most potent and/or selective inhibitors of HIV-induced cytopathogenicity (in order of decreasing selectivity: 3'-azido-3'-deoxythymidine (AZT), 3'-azido-2',3'-dideoxyuridine (AzddUrd), 3'-azido-2',3'-dideoxy-5-methylcytidine (AzddMeCyd), 3'-fluoro-ddUrd (FddUrd), 3'-fluoro-ddThd (FddThd), the N4-hydroxylated derivative of AzddMeCyd and the N4-methylated derivative of AzddMeCyd. Among the purine 2',3'-dideoxynucleosides, 3'-azido-2',3'-dideoxyguanosine (AzddGuo), 3'-fluoro-ddGuo (FddGuo), and 3'-fluoro-2,6-diaminopurine 2',3'-dideoxynucleoside (FddDAPR) were the most selective inhibitors of HIV replication.
