A reaction mode of imines derived from naphthalene-1-carbaldehyde and acyclic alpha,beta-unsaturated aldehydes with organolitium reagents was dependent on the characteristic nature of a substituent on the imine nitrogen atom. An imine having an electron-withdrawing aryl group on the nitrogen atom behaves as a 1,2-directing imine toward organolithium reagents. In contrast, an imine bearing an alkyl
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.
