  An Efficient Synthesis of Cyclic IDP- and Cyclic 8-Bromo-IDP-Carbocyclic-Riboses Using a Modified Hata Condensation Method To Form an Intramolecular Pyrophosphate Linkage as a Key Step. An Entry to a General Method for the Chemical Synthesis of Cyclic ADP-Ribose Analogues¹

  摘要：

  An efficient synthesis of cyclic IDP-carbocyclic-ribose (3! and its 8-bromo derivative 6, as stable mimics of cyclic ADP-ribose, was achieved, and a condensation reaction with phenylthiophosphate-type substrate 15 or 16 to form an intramolecular pyrophosphate linkage was a key step. N-1-Carbocyclic-ribosylinosine derivative 28 and the corresponding 8-bromo congener 24 were prepared via condensation between N-1-(2,4-dinitrophenyl)inosine derivative 17 and a known optically active carbocyclic amine 18. Compounds 24 and 28 were then converted to the corresponding 5''-phosphoryl-5'-phenylthiophosphate derivatives 15 and 16, respectively, which were substrates for the condensation reaction to form an intramolecular pyrophosphate linkage. Treatment of 8-bromo substrate 15 with It or AgNO3 in the presence of molecular sieves 3A (MS 3A) in pyridine at room temperature gave the desired cyclic product 12 quantitatively, while the yield was quite low without MS. The similar reaction of 8-unsubstituted substrate 16 gave the corresponding cyclized product 32 in 81% yield. Acidic treatment of these cyclic pyrophosphates 12 and 32 readily gave the targets 6 and 3, respectively. This result suggests that the construction of N-1-substituted hypoxanthine nucleoside structures from N-1-(2, 4-dinitrophenyl)ino sine derivatives and the intramolecular condensation by activation of the phenylthiophosphate group with I-2 or AgNO3/MS 3A combine to provide a very efficient route for the synthesis of analogues of cyclic ADP-ribose such as 3 and 6. Thus, this may be an entry to a general method for synthesizing biologically important cyclic nucleotides of this type.

• Concise synthesis of novel acyclic analogues of cADPR with an ether chain as the northern moiety

  日期：——

  To study the properties of hydrolysates of cyclic adenosine diphosphate ribose (cADPR), a series of novel acyclic analogues of cADPR with an ether chain as the northern moiety and 8-substituted adenine or hypoxanthine as the base moiety were synthesized via an N1 substitution construction, followed by bisphosphorylation, phosphoramidition or pyrophosphorylation. These compounds also provide various precursors for synthesizing cADPR analogues.

  An efficient synthesis of cyclic IDP-carbocyclic-ribose, as a stable mimic for cyclic ADP-ribose, was achieved. N-1-Carbocyclic-ribosylinosine derivative 15, prepared from N-1-(2,4-dinitrophenyl)inosine derivative 10 and an optically active carbocyclic amine 11, was converted to 8-bromo-N-1-carbocyclic-ribosylinosine bis-phosphate derivative 20. Treatment of 20 with I-2 in the presence of molecular sieves in pyridine gave the desired cyclic product 8 quantitatively, which was deprotected and reductively debrominated to give the target cyclic IDP-carbocyclic ribose (3).
