  Unsaturated phosphonates as acyclic nucleotide analogs. Anomalous Michaelis-Arbuzov and Michaelis-Becker reactions with multiple bond systems

  摘要：

  Reaction of adenallene (4a) with methanesulfonyl chloride in pyridine afforded 4'-chloro-4'-deoxyadenallene (6a). A similar reaction with toluene-4-sulfonyl chloride (NEt3, CH2Cl2) led to elimination of the unsaturated moiety and formation of N9-(4-toluenesulfonyl)adenine (8a). Michaelis-Arbuzov reaction of E- and Z-unsaturated chlorides 13a and 16b with triethyl phosphite afforded phosphonates 14a and 17b. Dealkylation of the latter products, coupled in case of 17b with acid hydrolysis, led to phosphonic acids 15a and 18. By contrast, Michaelis-Arbuzov reaction with butynyl chlorides 19a and 19b led to elimination of unsaturated moiety and alkylation of the released heterocyclic bases to give N9-ethyl derivatives 20a and 20b. In the presence of iodide ion, N9-(2,3-butadien-1-yl)adenine (30a, from 19a) and/or unsaturated diphosphonates 25a and 25b were obtained. The Michaelis-Arbuzov reaction of chloroallene 6a led to 2'-phosphonate 33a which, after dealkylation, afforded phosphonic acid 35a. When iodide ion was present, both 2'- and 4'-phosphonates 33a and 36a were obtained. Compound 36a was also prepared by Michaelis-Becker reaction of chloroallene 6a with sodium diethyl phosphite in THF-HMPA. In DMSO, both phosphonates 33a and 36a were formed. Under similar conditions (DMF), chlorobutyne 19a gave 4'-phosphonate 36a. Dealkylation of 36a furnished phosphonic acid 37a. Adenallene (4a) and diethyl chlorophosphite in pyridine afforded phosphonate 33a whereas butynol 39a afforded only adenine (10a). The probable reaction course of these transformations and spectral properties of the reaction products will be discussed.

• Phosphodiester Amidates of Allenic Nucleoside Analogues:  Anti-HIV Activity and Possible Mechanism of Action

  Lipophilic phosphodiester amidates 2a, 2b, 4a, 4b, and 6 derived from anti-HIV agent adenallene 1a, 3a, inactive hypoxallene 1b, 3b, and 9-(4-hydroxy-2-butyn-1-yl)adenine (5) were synthesized and studied as inhibitors of HIV-1 in ATH8 cell system. All phosphodiester amidates were more biologically active than their parent nonphosphorylated compounds. Analogues 2a and 4a derived from (+/-)-adenallene 1a and (R)-enantiomer 3a are effective anti-HIV agents with EC(50) approximately 0.88 and 0.21 mu M, respectively. Both analogues are 16 and 28 times more effective than parent-compounds 1a and 3a, respectively. Some anti-HIV activity of hypoxallene derivatives 2b and 4b was noted in the range of 0.1-10 mu M but the dose-response relationship was poor. Phosphodiester amidate analogue 6 also exhibited anti-HIV activity in the range of 0.1-100 mu M, but this effect was accompanied by cytotoxicity. Hydrolytic studies performed at pH 9.8 and with pig liver esterase at pH 7.4 have shown that analogue 2a gives adenallene 4'-phosphoralaninate (10a) as the major product. These results can be interpreted in terms of initial hydrolysis of phosphodiester amidates 2a, 2b, 4a, 4b, and 6 catalyzed by intracellular esterase(s) to give stable phosphomonoester amidate intermediates with a free carboxyl group. The results obtained with hypoxallene phosphoramidates 2b and 4b indicate-that the aminosuccinate-fumarate enzyme system responsible for activation of AIDS drug ddIno (didanosine, Videx) can also, albeit less efficiently, activate hypoxallene 4'-phosphate (9b) and the respective (R)-enantiomer released inside the HIV-infected cells.
