Naphthyridine compounds and their use as inhibitors of HPK1 are described. The compounds are useful in treating HPK1-dependent disorders and enhancing an immune response. Also described are methods of inhibiting HPK1, methods of treating HPK1-dependent disorders, methods for enhancing an immune response, and methods for preparing the naphthyridine compounds.

This work describes an efficient synthesis of enantiomericallypure (R)-2-aminomethylalanine, (R)-2-aminomethylnorvaline, (R)-2-aminomethylvaline, (R)-2-aminomethylleucine and (R)-2-aminomethylphenylalanine by electrophilic amination of chiral 2-cyanoesters with O-(diphenylphosphinyl)hydroxylamine followed by appropiate reduction and hydrolysis.
