The present invention relates generally to novel antiviral agents. Specifically, the present invention relates to compounds which can inhibit the protein(s) encoded by hepatitis B virus (HBV) or interfere with the function of the HBV replication cycle, compositions comprising such compounds, methods for inhibiting HBV viral replication, methods for treating or preventing HBV infection, and processes and intermediates for making the compounds.
An efficient method for highly stereo‐ and regioselective C‐3 alkenylation of indolizines and pyrrolo[1,2‐a]quinolones through RuII catalysis was developed. The alkenyl indolizines obtained in excellent to moderate yields. The synthetic utility of the products demonstrated through selective hydrogenation reactions.

A catalytic enantioselective conjugate addition of indolizines to enones is described. The chiral phosphoric acid (S)‐TRIP activates α,β‐unsaturated ketones, thereby promoting an enantioface‐differentiating attack by indolizines. Using this reaction, several alkylated indolizines were synthesized in good yields and with enantiomeric ratios of up to 98:2.
Methods to diversify indolizines are valuable for the discovery of medications and fluorescent molecules. The utilization of copper-catalyzed asymmetric propargylation to install a terminal alkyne handle on indolizine heterocycle is reported. This method delivers C3-propargylation products from C2-substituted indolizines or C1-propargylation products from C2,C3-disubstituted indolizines through a stereoconvergent
