Abstract
Bis(dichlorophosphino)methane was converted to a β,γ-methylenetriphosphitylating reagent. The reagent was immobilized on aminomethyl polystyrene resin-bound linker of 4-acetoxy-3-phenylbenzyl alcohol to afford a polymer-bound β,γ-methylenetriphosphitylating reagent, which was reacted with unprotected nucleosides followed by oxidation with tert-butyl hydroperoxide, deprotection of cyanoethoxy groups with DBU, and acidic cleavage, to produce 5'-O-β,γ-methylene triphosphate nucleosides in 53-82% overall yields. Among all the compounds, cytidine 5'-O-β,γ-methylenetriphosphate inhibited completely RNase H activity of HIV-1 reverse transcriptase at 700 μM.

Abstract
Chloromethyl polystyrene resin was reacted with 5-hydroxysalicylaldehyde in the presence of potassium carbonate to afford polymer-bound 2-hydroxybenzaldehyde. Subsequent reduction with borane solution produced polymer-bound 2-hydroxybenzyl alcohol. The reaction of immobilized 2-hydroxybenzyl alcohol with appropriate phosphitylating reagents yielded solid-phase cycloSaligenyl mono-, di-, and triphosphitylating reagents, which were reacted with unprotected nucleosides, followed by iodine oxidation, deprotection of cyanoethoxy groups, and the basic cleavage, respectively, to afford 5'-O-nucleoside mono-, di-, and triphosphoramidates in 52-73% overall yield.

Abstract
Four classes of phosphitylating reagents were subjected to reactions with aminomethyl polystyrene resin-bound p-acetoxybenzyl alcohol to yield the corresponding polymer-bound mono-, di-, tri-, and tetraphosphitylating reagents. The solid-phase reagents were reacted with unprotected nucleosides (e.g., thymidine, adenosine, 3'-azido-3'-deoxythymidine, cytidine, or inosine) in the presence of 5-(ethylthio)-1H-tetrazole. Polymer-bound nucleosides underwent oxidation with tert-butyl hydroperoxide, deprotection of cyanoethoxy groups with DBU, and the acidic cleavage, respectively, to afford 5',5'-dinucleoside mono-, di-, tri-, and tetraphosphodiesters in 59-78% yield.

Abstract
A beta-triphosphitylating reagent was subjected to reaction with aminomethyl polystyrene resin-bound p-acetoxybenzyl alcohol to yield the corresponding polymer-bound beta-triphosphitylating reagent. The solid-phase reagent was reacted with unprotected nucleosides (e.g., 3'-azido-3'-deoxythymidine, cytidine, thymidine, uridine, inosine, or adenosine) in the presence of 1H-tetrazole. Polymer-bound nucleosides underwent oxidation with t-butyl hydroperoxide, deprotection of cyanoethoxy groups with DBU, and the acidic cleavage, respectively, to afford only monosubstituted 5'-O-beta-triphosphorylated nucleosides.

Abstract
Aminomethyl polystyrene resin was reacted with 4-(5'-formyl-2'-hydroxyphenyl)benzoic acid and 4-(5'-formyl-2'-hydroxyphenyl)phenyl propionic acid, respectively, in the presence of 1-hydroxybenzotriazole and 1,3-diisopropylcarbodiimide to yield polymer-bound benzaldehydes. The phenolic group in resins was acetylated with acetic anhydride to afford two polymer-bound 4-acetoxybenzaldehydes. The reductive amination of polymer-bound linkers by amines and sodium triacetoxyborohydride, followed by sulfonylation with arylsulfonyl chloride derivatives in the presence of pyridine and the cleavage with TFA/DCM/H2O, produced pure sulfonamides.

Abstract
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.

A number of unprotected carbohydrates and nucleosides were reacted with the polymer-bound reagents. Oxidation with tert-butyl hydroperoxide or sulfurization with Beaucage's reagent, followed by removal of cyanoethoxy group with DBU and the acidic cleavage, respectively, afforded only one type of monosubstituted nucleoside and carbohydrate diphosphates, dithiodiphosphates, triphosphates, and trithiotriphosphates with high regioselectivity.

Abstract
Two classes of aminomethyl polystyrene resin-bound linkers of p-acetoxybenzyl alcohol were subjected to reactions with 2-cyanoethyl N,N-diisopropylchlorophosphoramidite to produce the corresponding polymer-bound phosphitylating reagents. These were reacted with a number of unprotected nucleosides and carbohydrates in the presence of 1H-tetrazole. Oxidation with tert-butyl hydroperoxide followed by removal of the cyanoethoxy group with 1,8-diazabicyclo[5.4.0]undec-7-ene afforded the corresponding polymer-bound phosphate diesters. Acidic cleavage of the p-acetoxybenzyl alcohol linker yielded monophosphorylated products with high regioselectivity and trapped linkers on the resins that can be reused.
