  N-Monoalkylation of Tetra-O-benzyl-D-arabinonamide: Synthesis of Some Open-Chain Analogues ofN-Acetylneuraminic Acid and Their Evaluation as Sialidase Inhibitors

  摘要：

  N-Arabinonoylglycine 2, its phospho analogue (arabinonoylamino)methylphosphonate 14, N-arabinonoyltaurine salt 18, and [2-(arabinonoylamino)ethylidene]bis[phosphonic acid] 22 have been synthesized from D-arabinose in seven (2 or 14), and eight steps (18 or 22a), respectively. With the exception of the salt 22b, none of these compounds showed a significant inhibitory activity in vitro against the sialidases of Vibrio cholerae, Salmonella typhimurium, or Influenza A (N9), or B (B/Lee/40) virus. Ammonolysis of the oxosulfonate 8 obtained by oxidation of the hydrogensulfite adduct 7 of 2,3,4,5-tetra-O-benzyl-aldehydo-D-arabinose (6) yielded the primary amide 9 (64% from 6),which was alkylated with the triflates 10 or 11 of benzyl glycolate and dibenzyl hydroxymethylphosphonate, respectively, to give the protected N-arabinonoylglycinate 12 and the (arabinonoylamino)methylphosphonate 13 (45 and 90%, resp.), N-Alkylation of 9 with 2-bromoethyl triflate 15 followed by nucleophilic displacement with sodium sulfite yielded the protected taurine analogue 17 (21% from 9), whereas the protected tetraethyl bis[phosphonate] 20 was formed in 90% yield by 1,4-addition of 9 to tetraethyl ethenylidenebis[phosphonate] 19. Debenzylation of 12 and 13, followed by purification by reversed-phase HPLC gave the triethylammonium salt of N-(D-arabinonoyl)glycine (2) and triethylammonium (D-arabinonoylamino)methylphosphonate (14b), respectively, whereas the deprotection of 17 afforded the N-(D-arabinonoyl)taurine salt 18. Debenzylation of 20, followed by treatment with Me3SiBr and hydrolysis of the resulting silyl ester gave the bis[phosphonic acid] 22a (3 steps, 88%).
