Abstract
An asymmetric propargylic alkylation of α-cyanocarbonyls is developed for the first time under cooperative Cu(I) and organocatalysis. With ethynyl benzoxazinanones as the propargylic electrophile, this decarboxylative doubly stereoconvergent reaction evades alkyne hydroamination to furnish acyclic α-propargylic cyanocarbonyls, bearing vicinal tertiary and quaternary stereocenters, with high diastereo- and enantioselectivity (up to >20:1 dr and 99.5:0.5 er).

Angew Chem Int Ed Engl 2024; 63:e202402038.

Abstract
A novel enantioselective Tsuji-Trost-type cross coupling reaction between gem-difluorinated cyclopropanes and N-unprotected amino acid esters enabled by synergistic Pd/Ni/chiral aldehyde catalysis is presented herein. This transformation streamlined the diversity-oriented synthesis (DOS) of optically active α-quaternary α-amino acid esters bearing a linear 2-fluoroallylic motif, which served as an appealing platform for the construction of other valuable enantioenriched compounds. The key intermediates were confirmed by HRMS detection, while DFT calculations revealed that the excellent enantioselectivity was attributed to the stabilizing non-covalent interactions between the Pd(II)-π-fluoroallyl species and the Ni(II)-Schiff base complex.

Abstract
An asymmetric linear selective allylic alkylation of vinylaziridines with 3-aryl oxindoles has been developed by using a chiral oxamide-phosphine (COAP-Bn-OMe-p)/palladium complex in methanol, which furnished a wide variety of 3,3-disubstituted oxindole derivatives in good yields with excellent regio- and enantioselectivities.

Abstract
Synergistic catalysis has emerged as one of the most powerful tools for stereodivergent formation of Csp3 -Csp3 bonds bearing vicinal stereocenters. Despite the many successes that have been achieved in this field, stereodivergent Csp3 -Csp3 coupling reactions involving stabilized nucleophiles remain challenging because of the competing single-catalysis pathway. Herein, we report a synergistic palladium/phase-transfer catalyst system that enables diastereodivergent Csp3 -Csp3 coupling reactions of 1,3-dienes with stabilized nucleophile oxindoles. Both the syn and anti coupling products, bearing quaternary and tertiary vicinal stereocenters, could be selectively produced in good yields with high enantio- and diastereoselectivities. Non-covalent activation of the stabilized nucleophile via chiral ion pair in a biphasic system is a crucial success factor in achieving diastereodivergence.
