Asymmetric Synthesis of Halocyclized Products by Using Various Catalysts: A State‐of‐the‐Art Review

Abstract Halogens play a crucial part in synthetic organic chemistry. Halo‐cyclized products hold numerous applications in the pharmaceutical industries, agrochemicals, natural product synthesis, and material chemistry. Thus, this review will discuss the role of various catalysts, such as from metal‐catalysts to organocatalysts, under different conditions to synthesize various halocyclized products. The synthesis and catalytic mechanisms underlying the different asymmetric transformations will also be covered by emphasizing the enantioselectivities, diastereoselectivities, and regioselectivities from the existing pieces of literature.
