摘要：
Conformationally constrained analogues 2a and ent-2a of 9-(difluorophosphonopentyl)guanines 1, a multi-substrate analogue inhibitor of PNP, were prepared from optically active trans-1-(diethoxyphosphinyl)difluromethy-2-hydroxymethylcyclopropanes (+)-6 and (-)-6, Enzymatic double resolution was applied to obtain (+)-6 and (-)-6 with high enantiomeric purity. Inhibitory activity of 2a and ent-2a were found to be 2400-fold less potent than 1. (C) 1997 Elsevier Science Ltd.
