Abstract
The rhodium(II)-carbenoid mediated transformation of diazocarbonyl compounds is well recognized as a useful process for the facile formation of carbon-carbon and carbon-heteroatom bonds under mild reaction conditions. In this review, the incorporation of rhodium(II)-carbenoid transformations in the synthetic planning and the eventual application of rhodium(II) carbenoid reactions in the synthesis of natural products, non-natural compounds of medicinal importance, and advanced intermediates are discussed. Focus is placed on the use of intermolecular and intramolecular C-H and X-H insertion, intermolecular and intramolecular cyclopropanation, and tandem ylide (carbonyl, ammonium, oxonium, sulfonium) formation/1,3-dipolar cycloaddition, [2,3]-sigmatropic or Stevens [1,2]-rearrangement reactions as key step(s) in the synthetic routes.
