Methods for the synthesis of functionalized alkynylcyclopropanes

Data on methods for the synthesis of various classes of functionalized alkynylcyclopropanes (FACPs) reported in the last two decades are systematized. Synthetic routes to FACPs based on cyclopropanation of unsaturated compounds with various carbenes, carbenoids, and ylides are considered separately. Methods for introducing functional groups into the three-membered ring of alkynylcyclopropanes via metalation and elimination—addition processes as well as other synthetic routes to functionalized cyclopropanes are discussed.
