Abstract

original image

Make it spiro! Readily synthesized heteroatom-substituted spiro[3.3]heptanes generally show higher aqueous solubility than their cyclohexane analogues, and show a trend towards higher metabolic stability. The novel framework can be mounted onto scaffolds of druglike structures, such as fluoroquinolones, to afford active compounds with similar or even improved metabolic stability.
