Therapeutic combinations of hepatitis B virus (HBV) vaccines and a pyridopyrimidine derivative are described. Methods of inducing an immune response against HBV or treating an HBV-induced disease, particularly in individuals having chronic HBV infection, using the disclosed therapeutic combinations are also described. The invention provides therapeutic combinations or compositions and methods for inducing an immune response against hepatitis B viruses (HBV) infection.
The present disclosure relates generally to toll like receptor modulator compounds, such as diamino pyrido[3,2 D]pyrimidine compounds and pharmaceutical compositions which, among other things, modulate toll-like receptors (e.g. TLR-8), and methods of making and using them.

An efficient synthesis protocol is presented for accessing quaternized α-amino acids in chiral, nonracemic form viadiastereoselective malonate alkylation followed by C- to N-transposition. The key stereodifferentiating step involves a diastereoselective alkylation of an α-monosubstituted malonate–imidazolidinone, which is followed first by a chemoselective malonate PMB ester removal and then a Curtius

The reaction of 1,7-enynes, synthesised from α-amino acids, carried out with diazo compounds in the presence of the Cp*RuCl(cod) catalyst allowed the one-step preparation of various strained bicyclic pipecolic acid derivatives in good yields under mild conditions. The stereoselectivity of the created double bond depends on the nature of the diazoalkane, and the diastereoselectivity arises essentially

The regio- and stereodivergent asymmetric α-allylation of aldimine esters with racemic allylic alcohols was enabled by cooperative catalysis. The Et3B additive plays a significant role in ionizing allylic alcohols to form electrophilic metal-π-allyl species and simultaneously promotes the formation of nucleophilic Cu-ylides. Computational mechanistic studies revealed the role of the Et3B additive and
