Optimisation, scope and limitations of the synthesis of 5-aminoindolizines from oxazolo[3,2-a]pyridinium salts
In this letter, we report on our efforts to optimise the reaction conditions and to explore the scope and limitations of the preparation of 5-aminoindolizines starting from oxazolo[3,2-a]pyridinium salts and different amines to evaluate the utility for co
