Catalytic Enantioselective Formation of C−C Bonds by Addition to Imines and Hydrazones: A Ten-Year Update

Catalysis by Palladium Pincer Complexes

Catalytic enantioselective allylation of carbonyl compounds and imines.

Simple indole alkaloids and those with a nonrearranged monoterpenoid unit

The chiral π-allylpalladium complex 2a, prepared from exoethylidenenorpinane 7, catalyzed the allylation of diverse imines with allyltributylstannane in the presence of 1 equiv of water in good to high enantioselectivities. The catalyst prepared from a 1:1 mixture of (E)- and (Z)-7 was found to be consisting of two stereoisomers 2a and 2b in 1.3:1 ratio. On separation, 2a catalyzed the allylation of imines in much higher enantioselectivities than 2b, giving the same major enantiomer and thereby justifying the need to separate 2a free of 2b. We have achieved the highest separation ratio of >400:1 for 2a:2b by repeated recrystallizations. Isomerization of 2b to 2a during recovery of 2a from the filtrates was observed as more of 2a was recovered each time during recrystallization. Although dry THF was the best solvent, we tried various additives and found that addition of one equivalent of water gave the best results with respect to shorter reaction time, higher yields and enantioselectivities. Thus, we have...

Chiral Bis-π-allylpalladium Complex Catalyzed Asymmetric Allylation of Imines: Enhancement of the Enantioselectivity and Chemical Yield in the Presence of Water

The asymmetric allylation of imines with use of catalytic transition metals with chiral ligands should be a new frontier of the enantioselective C−C bond formation. So far allyltrimethylsilane, allyltrichlorosilane, and allyltrimethoxysilane have been commonly employed with use of either silane activators or dual silane−imine activators. However, tetraallylsilane is untouched in the allylation of aldimines. The first allylation of aldimines with the tetraallylsilane−TBAF−MeOH system with use of the bis-π-allylpalladium catalyst under catalytic, non-Lewis acid, essentially neutral and very mild reaction conditions has been achieved. The reaction is triggered by dual activation/promotion by TBAF and MeOH in which the fluoride anion activates the C−Si bond cleavage and MeOH promotes the facile protonation of intermediate palladium amide. Thus, the synthesis of chiral homoallylamines is achieved in a shorter reaction time and higher yields and enantioselectivities through an efficient, general, and reproducib...

The First Catalytic Asymmetric Allylation of Imines with the Tetraallylsilane−TBAF−MeOH System, Using the Chiral Bis-π-allylpalladium Complex

An asymmetric dihydroxylation route to enantiomerically pure norfluoxetine and fluoxetine

This review highlights the developments in palladium-catalyzed allylic C–H functionalization from early 2014 to the present date. π-Allylpalladium chemistry emphasizes the research originating from less appealing stoichiometric Pd(II) based allylic C–H activation to the present day green, step- and atom-economical and sustainable strategy, wherein the allylic hydrogen atom becomes the “leaving group”. This constitutes a direct C–H activation method, which is essentially catalytic in the presence of a terminal oxidant to regenerate the Pd(II)-species from Pd(0). The availability of chiral ligands, under oxidative conditions, has paved the way to realize asymmetric oxidative Tsuji–Trost allylic alkylations.

Catalytic allylic functionalization via π-allyl palladium chemistry

A mimic of the Wacker process for C═O bond formation in terminal olefins can be initiated by a combination of the Pd(II) and hypervalent iodine reagent, Dess–Martin periodinane to generate methyl ketones. This operationally simple and scalable method offers Markovnikov selectivity, has good functional group compatibility, and is mild and high yielding.
