TL;DR: This comprehensive review on cycloaddition reactions of enoldiazo compounds, with emphasis on methodology development, mechanistic insight, and catalyst-controlled chemodivergence, aims to provide inspiration for future discoveries in the field and to catalyze the application of enoldsiazo reagents by the wider synthetic community.

TL;DR: A copper-catalyzed B-H bond insertion reaction with amine- and phosphine-borane adducts was realized with high yield and enantioselectivity under mild reaction conditions.

TL;DR: A [3+3]-cycloaddition reaction was achieved with excellent yield and enantioselectivity under exceptionally mild conditions, which represents the first highly enantiOSElective base-metal-catalyzed vinylcarbene transformation.

TL;DR: A formal [3 + 3]-cycloaddition of enoldiazoacetates with donor-acceptor cyclopropanes was realized by the combination of a Lewis acid-catalyzed diastereoselective cycle and a subsequent rhodium-Catalyzed chemoselectives ring expansion.

TL;DR: High enantioselectivity and exclusive regiocontrol occurred with enoldiazoacetamides using a less sterically encumbered prolinate-ligated dirhodium(II) catalyst in reactions with N-substituted indoles without substituents at the 2- or 3-positions via a selective vinylogous addition process.
