Alkyne hydroamination triggered cyclizations: A powerful tool for the construction of biologically important structural motifs

This review focuses mainly on recent endeavors in the field of cyclizations triggered by the catalytic hydroamination (formal or direct) of alkynes. The new strategies developed offer an efficient and convenient entry to several heterocycles of biological importance.
