Synthesis, structural and spectroscopic characterization of thiophosphorodiamidates and effect of ZnCl2 on the hydrolysis of the P–N bond
摘要:
New N,N'-dibenzylthiophosphorodiamidate derivatives were synthesized from the corresponding thiophosphorodichloridate intermediates and benzylamine. Several compounds with formula 2-MeC6H4OP(S)(NHBn)(2) (6), 2-FC6H4OP(S)(NHBn)(2) (7), 2-ClC6H4OP(S)(NHBn)(2) (8), 4-MeC6H4OP(S)(NHBn)(2) (9) and 4-t-BuC6H4OP(S)(NHBn)(2) (10) were synthesized and characterized by H-1, C-13, P-31 NMR, IR, mass spectroscopy and elemental analysis. The single crystal X-ray diffraction studies of 6 and 7 have been described. ZnCl2 assisted P-N bond hydrolysis of thiophosphorodiamidates was investigated. (C) 2012 Elsevier Ltd.

Methods for the synthesis of 2-aryloxy(arylthio)- and 2-alkoxy(alkylthio)-2-thio(oxo)-1,3,2-oxazaphosphorinanes and theirN-substituted derivatives based on the reactions of the corresponding dichlorophosphates, dichlorothio-, and dithiophosphates with 3-aminopropan-1-ol or its substituted derivatives in the presence of Et3N or aqueous alkali under phase transfer catalysis conditions, as well as by
Preparation of a new phosphorylating agent: -(N-monomethoxytrxtylaminoethyl)--(-chlorophenyl)phosphorothioate and its application in oligonucleotide synthesis
phosphorylating agent, -(N-monomethoxytritylaminoethyl)--(-chlorophenyl)phosphorothioate (), was prepared. It was used for phosphorylation with a 5'-hydroxyl group of an oligonucleotide. After base labile protecting groups were removed, the partially deprotected oligonucleotide was separated and converted to the oligonucleotide with an aminoethyl or a phosphoryl group at the 5'-end by treatment with
Disclosed herein are phosphorothioate nucleotide analogs, methods of synthesizing phosphorothioate nucleotide analogs and methods of treating diseases and/or conditions such as viral infections, cancer, and/or parasitic diseases with the phosphorothioate nucleotide analogs.

Phosphorothioylation of 3′,5′-dihydroxyl ribonucleosides with O-(2-chlorophenyl) O, O-bis[6-(trifluoromethyl)-1-benzotriazolyl] phosphorothioate, followed by addition of N-methyl-imidazole and removal of protecting groups, gives ribonucleosides 3′,5′-cyclic phosphorothioates. The latter compounds could also be prepared by phosphorothioylation of 2′,3′,5′-trihydroxyl ribonucleosides.

adenylyl (3′→5′)-5′-thiouridines 12 and 13 were partially deprotected to 37 and 38, having a phosphorothioate linkage with a bridging sulfur [ribonucleoside-3′-O-PO2-S-5′-ribonucleoside] in order to examine the stability of this internucleotidyl linkage vicinal to a 2′ -hydroxyl function. The 2′-O-protected adenylyl(3′→5′)-5′- thiouridines 37 and 38 were found to be as stable as thymidylyl(3′→5′)-5′-thiothymiifine
