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。
