A series of imidazo[1,2-alpha]pyrazine derivatives was synthesized by condensation of alpha-halogenocarbonyl compounds and aminopyrazines. Various compounds resulted from competitive reactions or reagent isomerization and demonstrated in vitro uterine-relaxing and in vivo antibronchospasticactivities. On isolated atria, 5-bromoimidazo-[1,2-alpha]pyrazine showed positive chronotropic and inotropic
