The indium-mediated allylation of novel 3-(2-Boc-hydrazono)indolin-2-one derivatives, followed by a palladium-catalysed carboamination reaction, is described to afford unprecedented spirocyclic oxindoles in good yields. The method provides an efficient access to both cis and trans diastereoisomers of highly functionalized compounds, bearing an N-Boc, 5-substituted pyrazolidine ring at the C3-oxindole spiro junction. The versatility of the method is fully demonstrated starting from a series of substituted isatins and employing a variety of aryl halides in the key cyclization step.

An optimized catalyst system of [Pd2(dba)3] and AsPh3 efficiently catalyzes the Stille reaction between a diverse set of functionalized stannanes and halogenated mono-, di- and oligonucleotides. The methodology allows for the facile conjugation of short and long nucleic acid molecules with moieties that are not compatible with conventional chemical or enzymatic synthesis, among them acid-, base-, or fluoride-labile protecting groups, fluorogenic and synthetically challenging moieties with good to near-quantitative yields. Notably, even azides can be directly introduced into oligonucleotides and (deoxy)nucleoside triphosphates, thereby giving direct access to “clickable” nucleic acids.

A photoredox/palladium-cocatalyzed enantioselective alkylation of racemic secondary carbonates with 4-alkyl-1,4-dihydropyridines under visible light irradiation has been developed. The present study provides a method for the preparation of optically active diarylalkanes from racemic diarylmethyl carbonates by a dynamic kinetic asymmetric transformation (DYKAT). This photoredox/palladium dual catalysis strategy expands the scope of the asymmetric Pd-catalyzed benzylic substitution reaction and serves as its potential alternative and complement.

The development of new methodologies that enable chemo- and stereoselective construction of fluorinated substituents, such as the trifluoromethyl (CF3) group, plays an essential role in the synthesis of new pharmaceutical agents. The exceptional ability of the CF3 moiety to prevent in vivo metabolism as well as improve other pharmacological properties has led to numerous innovative strategies for installing this unique functional group. One potential yet underdeveloped approach to access these trifluoromethylated products is direct substitution of alpha-trifluoromethyl carbanions. Although the electron-withdrawing nature of the CF3 group should facilitate deprotonation of adjacent hydrogens, the propensity of the resulting carbanions to undergo alpha-elimination of fluoride renders this process highly challenging. Herein, we describe a new strategy for stabilizing and utilizing transient alpha-trifluoromethyl carbanions that relies on a neighbouring cationic pi-allyl palladium complex. These palladium-stabilized zwitterions participate in asymmetric [3 + 2] cycloadditions with a broad range of acceptors, generating valuable di- and trifluoromethylated cyclopentanes, pyrrolidines and tetrahydrofurans.
