Combining chiral elements: A novel approach to asymmetric phase-transfer catalyst design

A new dicationic asymmetric phase-transfer catalyst, designed by combining chiral elements, is described. Catalytic testing using standard glycine imino ester alkylations shows good yields and moderate enantioselectivities.

Counter-rotatable dual cinchona quinuclidinium salts and their phase transfer catalysis in enantioselective alkylation of glycine imines

Dual cinchona quinuclidinium salts with a diphenyl ether linker were synthesized and used as powerful asymmetric phase transfer catalysts in the α-alkylation of imines of glycine and alanine ester with 0.01-0.1 mol% loading (17 examples, 92-99% ee). Skewed conformers of dual quinuclidiniums at TS were proposed to rationalize their high efficiencyviaDFT calculations.

Improved access to chiral tetranaphthoazepinium-based organocatalysts using aqueous ammonia as nitrogen source

The class of 3,30-diaryl substituted tetranaphthobisazepinium bromides has found wide application as highly efficient C2-symmetrical phase-transfer catalysts (PTCs, Maruoka type catalysts). Unfortunately, the synthesis requires a lar

Synergistic Cu/Pd Catalysis for Enantioselective Allylation of Ketimine Esters: The Direct Synthesis of α-Substituted α-Amino Acids and 2H-Pyrrols

An efficient synergistic Cu/Pd catalyzed enantioselective α-allylation of acyclic ketimine esters has been reported, which provides an entry to nonproteinogenic α-allyl α-amino acids in high yield, exclusive regioselectivity, and excellent enantioselectivity. Moreover, the more challenging cyclic ketimine ester could also be employed as a nucleophile for the construction of 3,4-dihydro-2H-pyrrole derivatives bearing a quaternary stereogenic center using the same catalytic system.
