چکیده
We have developed catalytic allylation reactions of sulfonylimidates using allylic alcohols as allylating reagents. Stoichiometric amounts of neither activators nor bases are required in this reaction.

Diastereoselective allylation and crotylation of N-tert-butanesulfinyl imines with allylic alcohols.
The palladium-catalyzed allylation of N-tert-butanesulfinyl imines with allylic alcohols in the presence of InI as reducing reagent takes place with high diastereoselectivity in reasonable yields. The reaction with crotyl alcohol is totally regioselective, leading to the anti-diastereomer as the main reaction product.
متن کاملGold(I)-Catalysed Direct Thioetherifications Using Allylic Alcohols: an Experimental and Computational Study
A gold(I)-catalysed direct thioetherification reaction between allylic alcohols and thiols is presented. The reaction is generally highly regioselective (S(N)2'). This dehydrative allylation procedure is very mild and atom economical, producing only water as the by-product and avoiding any unnecessary waste/steps associated with installing a leaving or activating group on the substrate. Computa...
متن کاملAllylic sp3 C-H borylation of alkenes via allyl-Pd intermediates: an efficient route to allylboronates.
Palladium catalyzed allylic C-H functionalization was performed using exocyclic alkene substrates. Multi-component synthesis of stereodefined homoallylic alcohols could be performed using a reaction sequence involving allylic C-H borylation and allylation of aldehydes.
متن کاملDual nickel and Lewis acid catalysis for cross-electrophile coupling: the allylation of aryl halides with allylic alcohols† †Electronic supplementary information (ESI) available. CCDC 1515176. For ESI and crystallographic data in CIF or other electronic format see DOI: 10.1039/c7sc03140h
Controlling the selectivity in cross-electrophile coupling reactions is a significant challenge, particularly when one electrophile is much more reactive. We report a general and practical strategy to address this problem in the reaction between reactive and unreactive electrophiles by a combination of nickel and Lewis acid catalysis. This strategy is used for the coupling of aryl halides with ...
متن کاملIridium-catalyzed regioselective decarboxylative allylation of β-ketoacids: efficient construction of γ,δ-unsaturated ketones.
A highly regioselective protocol for the direct synthesis of γ,δ-unsaturated ketones from β-ketoacids and allylic alcohols was proposed and accomplished relying on the combination of [Ir(cod)Cl]2 and 10-camphorsulfonic acid via decarboxylative allylation.
