Solid-liquidPTC without added organic solvent promotes alkylation of purine derivatives leading in particular to an efficient synthesis of the antiviral DHPA. The location of the substituent on the ring was determined by analysis of coupling interactions through 2D δ-δ heteronuclear 1H 13C correlated NMR spectroscopy.
不添加有机溶剂的固液PTC促进嘌呤衍生物的烷基化,尤其导致抗病毒DHPA的有效合成。环上取代基的位置是通过2Dδ-δ杂核1 H 13 C相关NMR光谱分析耦合相互作用来确定的。

Abstract In research directed at the development of adenine triphosphate (ATP) analogs as potential glutamine synthetase (GS) inhibitors, adenine and allopurinol derivatives have been synthesized either as novel ATP analogs or as scaffolds for the construction of such analogs.
摘要 在旨在开发作为潜在谷氨酰胺合成酶 (GS) 抑制剂的三磷酸腺嘌呤 (ATP) 类似物的研究中,已合成腺嘌呤和别嘌呤醇衍生物作为新型 ATP 类似物或作为构建此类类似物的支架。

N-7-alkenylpurines have been synthesized by rearrangement of the corresponding N-allyl derivatives, often in good yields and with high stereoselectivity. Base promoted and transition metal mediated rearrangements have been studied. Simple allylpurines were easily rearranged with catalytic amounts of RuClH(CO)(PPh3)3. The efficiency of base promoted rearrangement was highly dependent on the detailed structure
N-9- 和 N-7- 烯基嘌呤是通过相应的 N-烯丙基衍生物的重排合成的,通常具有良好的产率和高立体选择性。已经研究了碱促进和过渡金属介导的重排。简单的烯丙基嘌呤很容易与催化量的 RuClH(CO)(PPh3)3 重排。碱促进重排的效率高度依赖于起始材料的详细结构,但这种反应经常以惊人的高 Z 选择性发生。
