Usage

Purification Methods

Purify it as for the diNa salt [Murray & Atkinson Biochemistry 7 4023 1968]. Dissolve 0.3g in dry MeOH (7mL) and 1M LiI (6mL) in dry Me2CO containing 1% of mercaptoethanol, and the Li salt is precipitated by adding Me2CO (75mL). The residue is washed with Me2CO (4 x 30mL) and dried at 55o/25mm. UV: max (HCl, pH 1.2) 257nm ( 14,800); (0.015M NaOAc, pH 4.8) 259nm ( 14,800); and (0.015 4OH, pH 10.1) 259nm ( 15,300).

Synthesis ofnucleoside 3'-thiophosphates in one step procedure

A mild and efficient one-step method of thiophosphorylation was devised for acid-sensitive nucleosides. The procedure is based on thiophosphorylation of nucleoside magnesium alkoxide by 2-chloro-2-thio-l,3,2-dioxaphospholane. The utility and efficiency of this method combined with deprotection of the resulting cyclic triester were demonstrated by its application to the synthesis of both adenosine 3'- and 5'thiophosphates. The procedure does not require protection of the exocyclic amino group and can be successfully used for the thiophosphorylation of nucleosides that are unusually sensitive to depurination.

Polymer-bound oxathiaphospholane: A solid-phase reagent for regioselective monothiophosphorylation and monophosphorylation of unprotected nucleosides and carbohydrates

(Chemical Equation Presented) Two polymers bound to N,N-diisopropylamino-1, 3,2-oxathiaphospholane were reacted with unprotected carbohydrates and nucleosides in the presence of 1H-tetrazole, followed by oxidation with tert-butyl hydroperoxide or sulfurization with Beaucage's reagent. The 1,3,2-oxathiaphospholane ring-opening with 3-hydroxypropionitrile, followed by treatment with DBU, afforded the corresponding monophosphate and monothiophosphate derivatives, respectively, through the elimination of polymer-bound ethylene episulfide. Reactions using this strategy offer the advantages of high regioselectivity, monosubstitution, and facile isolation and recovery of products.
