摘要

Small heteroaromatic rings are valuable monomers in drug discovery that can enable rapid access to novel and desirable chemical space. Installation of a synthetic handle on a heteroaromatic core may be difficult if steric and electronic factors are not in alignment with the desired transformation. Described are practical routes for the construction of 5-bromo-6- methyl imidazopyrazine (1) as well as 5-bromo and 5-chloro-6-methyl imidazopyridines ( ...
