Nucleophilic catalysts are widely used for acyl transfer reactions, but chiral variants can be difficult to design or synthesise. Here, the authors report catalysts with chirality imparted from a binaphtyl moiety with tert-alcohol unit that show both

We demonstrate that lithium hexamethyldisilazide (LiHMDS) acts as an effective base for deprotonative coupling reactions of toluenes with ketones to afford stilbenes. Various functionalities (halogen, OCF3, amide, Me, aryl, alkenyl, alkynyl, SMe, and

π-Allylpalladium complexes can not only serve as electrophilic allylating agents for a broad range of nucleophiles, but also nucleophilic allylating agents for electrophiles depending on their electronic environments. In contrast to these typical re

The dynamic parallel kinetic resolution (DPKR) of an α-ferrocenyl cation intermediate under the influence of a chiral conjugate base of a chiral phosphoric acid catalyst has been demonstrated in an SN1 type substitution reaction of a racemic ferroce
