The synthesis of amines is one of the most important areas of research in organic chemistry due to the prevalence of nitrogen atoms in many functional molecules, including natural products, pharmaceutical drugs, and agrochemicals. The synthesis of amines through rearrangement reactions has been heavily researched and discussed over the past few decades. One of the most comprehensive reviews of this topic was included in Science of Synthesis (Section 188.8.131.52). The purpose of this review is to provide an up-todate account of new methods and synthetic developments in amine rearrangement reactions within the last decade. Over this period of time, new chemistry has been developed which was not discussed in any particular section in the original account on this topic. Thus, this chapter serves as a supplementary document to the earlier review but is also a source of new synthetic strategies not discussed previously. The chapter is arranged in two sections: rearrangements from carbon to nitrogen, and rearrangements from nitrogen to carbon.
