Z-vinyl-iodide, recent literature. a halide-exchange reaction of vinyl bromides with potassium iodide proceeds smoothly in the presence of a copper catalyst under mild reaction conditions to provide the corresponding vinyl iodides stereospecifically and in good yields.. In organic chemistry, a vinyl iodide functional group (also known as iodoalkenes) is any alkene with an iodide substituent directly bonded to one of the alkene carbons (sp 2). vinyl iodides are versatile molecules that serve as important building blocks and precursors in organic synthesis., general description ethyl cis-3-iodoacrylate (cis-ethyl-β-iodoacrylate, ethyl (z)-β-iodoacrylate) is z-vinyl iodide derivative. it is reported to be prepared from ethyl propiolate by treating with sodium iodide. its suzuki coupling reaction with cyclic vinyl boronic acids has been studied..

A successful preparation of iodomethyltriphenylphosphorane is described. the wittig reaction of this phosphorane provides a simple 1-carbon homologation of an aldehyde to a z-vinyl iodide., corresponding z-vinyl iodide 4 as the major product (see esi†). with requisite 3 and 4 in hand, the copper-mediated amidation was examined next. surveying of current literature revealed the possibility of using catalytic cu(i)-systems for the formation of z-enamides especially in the presence of sensitive functional. Because of the susceptibility of 12 to protodestannylation, the (z)-vinyl iodide (13), prepared in quantitative yield from 12, was used as a substrate for c-c bond formation. various types of ..., this letter describes a palladium-catalyzed cyclization of vinyl iodide-tethered allensulfonamide in the presence of alkylol, which provides a facile access to 2-alkoxy-3-methylene-tetrahydropyridine. the asymmetric version of this reaction has also been preliminarily realized with up to 81% enantioselectivity when chiral bisphosphine ligands ....

Efficient access to z-vinyl iodide 35 bearing an adjacent tertiary ester. electron-rich alkenes are also capable of ketyl radical coupling, including those substituted with si (36)orb(37). an an-tioxidant, vitamin e, was also incorporated in the alkyne acceptor (38) without inhibiting this mild ketyl radical coupling., the key step in the concise syntheses of calystegine b2 and its c-2 epimer calystegine b3 was the construction of cycloheptanone 8via an intramolecular nozaki-hiyama-kishi (nhk) reaction of 9, an aldehyde containing a z-vinyl iodide. vinyl iodide 9 was obtained by the stork olefination of aldehyde 10, derived from carbohydrate starting ....

Abstract: the total synthesis of seven members of the lapidilectine and grandilodine family of alkaloids has been accomplished in racemic and enantiopure form without protection/deprotection of functional groups. the two key steps, an 8-endo-dig hydroarylation and ...
