The activation of a substrate by a chiral catalyst is now regarded as one of the most powerful
strategies that can be employed in the art of asymmetric synthesis. 1 The development of …

Figure 73: The proposed catalyst/substrate interaction shown in Figure 73 corresponds to
the related sulfoxidation catalyzed by chiral phosphoric acid PA 5 (ref 133). Please note that …

Catalytic enantioselective introduction of a propargyl group constitutes one of the most
important carbon–carbon forming reactions, as it is versatile to be transformed into diverse …

Enantioselective allylation is a highly used organic reaction to prepare chiral homoallylic
alcohols and amines, which serve as important building blocks in the synthesis of a variety …

Chiral phosphoric acids (CPAs) have been used as efficient organocatalysts since the first
examples were reported 18 years ago by Akiyama and Terada. Although they were …

The development of α, α-disubstituted crotylboronate reagents is reported. Chiral Brønsted
acid-catalyzed asymmetric aldehyde addition with the developed E-crotylboron reagent …

Bimetallic Pd/Cu and Pd/Ag catalytic systems were used for borylation of propargylic alcohol
