Deacylative Allylation: Allylic Alkylation via Retro-Claisen Activation [PDF]
, 2016 A new method for allylic alkylation of a variety of relatively nonstabilized carbon nucleophiles is described herein. In this process of “deacylative allylation”, the coupling partners, an allylic alcohol and a ketone pronucleophile, undergo in situ ...

Highly diastereoselective Barbier allylation and iminium cyclization: a simple entry to bicyclic and tricyclic piperazinones [PDF]
, 2008 Barbier allylation of 5,6-dihydropyrazin-2(1H)-ones leads to a single isomer of 3-allylpiperazin-2-ones in high yields. Further Pictet–Spengler–Grieco cyclization of 3-allylpiperazin-2-ones with aldehydes provides bicyclic and tricyclic piperazinones ...

Further exploration of the heterocyclic diversity accessible from the allylation chemistry of indigo
Beilstein Journal of Organic Chemistry, 2015 Diversity-directed synthesis based on the cascade allylation chemistry of indigo, with its embedded 2,2’-diindolic core, has resulted in rapid access to new examples of the hydroxy-8a,13-dihydroazepino[1,2-a:3,4-b']diindol-14(8H)-one skeleton in up to 51%

Rhodium-Catalyzed Enantio- and Regioselective Allylation of In-doles with gem-Difluorinated Cyclopropanes [PDF]
The use of gem-difluorinated cyclopropanes (gem-DFCPs) as fluoroallyl surrogates under transition-metal catalysis has drawn considerable attention recently but such reac-tions are restricted to producing achiral or racemic mono-fluoroalkenes.

Nickel-catalyzed α-allylation of aldehydes and tandem aldol condensation/allylation reaction with allylic alcohols [PDF]
, 2017 An additive-free nickel-catalyzed alpha-allylation of aldehydes with allyl alcohol is reported. The reaction is promoted by 1 mol% of in situ formed nickel complex in methanol, and water is the sole by-product of the reaction. The experimental conditions
