Herein, we report a versatile {approach|method|strategy} for theendocyclic ring-opening of bicyclic vinylcyclopropanes triggered by Heckarylations. {Key|Important|Crucial|Essential} step for this transformation {is a|is really a|is actually a|can be a|is often a|is usually a} [1,3]-migratory shift of Pdallowing the ring expansion of cyclopropanated pyrroles, piperidines, furans aswell as cyclopentadienes to grant access {to the|towards the|for the} corresponding1,2-dihydropyridines, 2H-pyrans,{2|two},3-dihydro-1H-azepines and1,4-cyclohexadienes, respectively. {Additionally|In addition|Furthermore|Moreover|Also|On top of that}, gem-disubstitutedcyclopropanated furans showed unexpected behavior by givingdiastereoselectively asymmetrically substituted dienes. Mechanistic {studies|research} andtheoretical calculations point towards a facile [1,3]-migratory shiftof Pd along the cyclopropane moiety, which can {successfully|effectively} compete {with the|using the|with all the|together with the} usualtermination step of a Heck reaction {via|by way of|through|by means of} a syn-b-hydride elimination. 2848-78-4 In stock 1174020-44-0 site PMID:35116795
