Abstract
Molecular rearrangements are important tools to increase the molecular diversity
of new bioactive compounds, especially in the class of heterocycles. This review deals
specifically with a very famous and widely applicable rearrangement known as the Dimroth
Rearrangement. Although it has originally been observed for 1,2,3-triazoles, its amplitude
was greatly expanded to other heterocycles, as well as from laboratory to large
scale production of drugs and intermediates. The reactions that were discussed in this review
were selected with the aim of demonstrating the windows that may be open by the
Dimroth's rearrangement, especially in what regards the development of new synthetic approaches
toward biologically active compounds.
Keywords:
Heterocycles, synthesis, azoles, 1, 2, 3-triazoles, pyrimidine, quinazoline.
