7 of cADPR (1), a cyclic nucleotide bis(phosphate) involved in Ca2+ metabolism, was prepared starting from 2′,3′-isopropylideneinosine (8) which was alkylated at N-1, leading to the intermediate 11. Bis(phosphorylation) of 11 through two alternative procedures, followed by phosphate deprotection steps, afforded derivatives 15 and 16, the substrates for the intramolecular pyrophosphate bond formation
cADPR (1) 的新类似物 7 是一种参与 Ca2+ 代谢的环核苷酸双(磷酸酯),从 2',3'-异亚丙基肌苷 (8) 开始制备,其在 N-1 处被烷基化,产生中间体 11。通过两个替代程序对 11 进行双(磷酸化),然后进行磷酸脱保护步骤,得到衍生物 15 和 16,它们是分子内焦磷酸键形成的底物。15 和 16 均以高产率转化为衍生物 17,最终脱保护得到目标化合物 7。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2002)
