  Independent Synthesis and Fate Studies of Impurities in Process Intermediates of the Anti-AIDS Drug d4T

  摘要：

  Impurities in isolated intermediates in a process to prepare d4T were identified, independently synthesized, and then taken through the process to determine their ultimate fate. Some of the products from these fate studies were also independently synthesized and used in the validation of impurity assay methods.

  addition of dialkyl-hydroxymethylphosphonate to the protected 4′,5′-didehydronucleosides resulted in an epimeric mixture of 4′-dialkylphosphonomethoxy derivatives of 2′,5′-dideoxynucleosides, novel analogues of 2′-deoxynucleoside 5′-monophosphates. Several types of electrophiles (pyridinium tosylate, NIS, NBS, MCPBA and others) were evaluated in addition reactions with 4′,5′-didehydrothymidine. Out

  The anti-AIDS drug d4T was prepared without contamination of the nucleoside bond cleaved by-product thymine from the readily available ribonucleoside 5-methyluridine (1). This was accomplished by using a new strategy which involved a regio/stereo controlled beta-elimination of trans-bromoacetates 6. (C) 1998 Bristol-Myers Squibb Company.

  3'.5'-Bis-O-(4-tolylsulfonyl)-thymidine and -2'-deoxyuridine (13a and 13b) reacted with sodium ethoxide in boiling ethanol to give the corresponding ethoxy-oxetanes 12a and 12b in 67 and 66% overall yield for the two-step processes starting from thymidine 4a and 2'-deoxyuridine 4b; respectively. Treatment of the ethoxy-oxetanes 12a and 12b with hydrogen sulfide and N-1,N-1,N-3,N-3- tetramethylguanidine in dry pyridine solution gave the 2-thiothymine- and 2-thiouracil-derived oxetanes 19a and 19b in 62 and 68.5% yield, respectively. When the latter compounds were treated with potassium tert-butoxide in dimethyl sulfoxide, the corresponding 2',3'-didehydro-2',3'-dideoxynucleosides (d4 nucleosides) 10a and 10b were obtained in 66 and 60% yield. respectively. The 2-thiothymine-derived oxetane 19a was converted via the 5-methyl-2-thiocytosine-derived oxetane 21a into the 5-methyl-2-thiocytosine-derived d4 nucleoside 11a in 59.5% overall yield; the 2-thiouracil-derived oxetane 19b was similarly converted into the 2-thiocytosine- and 4-N-methyl-2-thiocytosine-derived d4 nucleosides 11b and 23 in 51 and 50% overall yield, respectively. Finally, the ethoxy-oxetane 12b was converted into the corresponding amino- and methylamino-oxetanes 25a and 25b in 74 and 83% yield, respectively. The latter compound. 25b, was successfully converted into the 2-N-methylisocytosine-derived d4 nucleoside 26b in 62% yield.

  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.

  The title compound 4 was quantitatively converted into the isomeric furan derivative 5 under relatively mild acidic conditions; when compound 4 was treated with 3-chloroperbenzoic acid in dichloromethane and sodium hypochlorite in aqueous dioxane, compounds 9 and 11, respectively, were obtained. Both compounds were isolated in 48% yield.
