1-substituted, 2-substituted 1H-imidazo[4,5-c]-quinolin-4-amines are disclosed. These compounds function as antiviral agents, they induce biosynthesis of interferon, and they inhibit tumor formation in animal models. This invention also provides intermediates for preparing such compounds, pharmaceutical compositions containing such compounds, and pharmacological methods of using such compounds.

A facile and convergent approach has been developed for the stereoselective construction of biologically important polyhydroxylated 2‐acyl indolizidine framework using aza‐Cope rearrangement–Mannich cyclization as a key step. The generality of this methodology is demonstrated with various lactol‐tosylates derived from carbohydrates. The presented method provides an easy access to indolizidine‐ and
