Reductive umpolung reactions of saturated and unsaturated carbonyl compounds enable
the direct synthesis of 1, 2-, 1, 4-, 1, 6-, etc. substituted carbon frameworks that are difficult to …

Georg Frey, Hieu-Trinh Luu, Plamen Bichovski, Markus Feurer, and Jan Streuff* α-Aminated
carbonyl compounds represent important building blocks for the synthesis of bioactive …

Simple, convenient methods have been developed using readily available, easy-to-handle
reagents to access a variety of chiral amino alcohols and amines, which have considerable …

d-(–)-Camphorquinone imines prepared using methanolic ammonia, ethanol amine, exo-(–)-
bornylamine, ethylene diamine, propylene diamine, and trans-(R, R)-1, 2 …

The reaction of chiral imines, derived from aromatic aldehydes and (S)-valinol, with a
Grignard reagent in the presence of Mg (0) afforded imino-pinacol coupling products instead …

Racemic 2, 3-diaryl-1, 4-diazabicyclo [2.2. 2] octane (DABCO) derivatives are synthesized
from the readily accessible piperazines in 50–64% yield by cyclization using ethylene …

Chiral titanium complexes are low-cost, low-toxicity and high-efficiency catalysts. Impressive
progress on enantioselective titanium-catalysed transformations has been achieved in the …

Abstract Auf zwei Arten: Eine Titan (III)‐katalysierte reduktive radikalische Cyclisierung von
Iminonitrilen wurde entwickelt, die zur direkten Synthese von α‐aminierten Ketonen führt. Je …

A library of chiral hemisalen ligands (30) was realized. The ligands were synthesized by the
condensation of salicylaldehyde derivatives with amino-alcohols (amino-indanol or …

The reaction of phenylsilane (PhSiH3) and titanium (IV) isopropoxide [Ti (OiPr) 4] generates
low‐valent titanium alkoxides that reduce and reductively couple imines. The C–C coupling …
