title: Synthetic study on carbocyclic analogues of cyclic ADP-ribose.
abstract: Cyclic ADP-ribose (cADPR, 1) is a newly discovered general mediator involved in Ca2+ signaling. Carbocyclic analogues of 1, namely, 2 and 3, were designed as a stable isosteres of 1, and their synthesis was studied. The reaction of a triflate 9 which was derived from known diol 4, and inosine derivative 10 gave desired N1-alkyl derivative 11 in 38% yield, and then it was converted to diphosphate derivative 12.
