Asymmetric catalysis has been recognized as the most enabling strategy for accessing
chiral molecules in enantioenriched forms. Catalytic asymmetric dearomatization is an …

In this review, we summarize the origin and advancements of iridium-catalyzed asymmetric
allylic substitution reactions during the past two decades. Since the first report in 1997, Ir …

Chiral indole derivatives such as indolines and indolenines are important heterocyclic
frameworks which constitute the core structures of many natural products and bioactive …

Highly selective separation and/or purification of acetylene from various gas mixtures is a
relevant and difficult challenge that currently requires costly and energy‐intensive …

The enantioselective synthesis of spirocycles has long been pursued by organic chemists.
Despite their unique 3D properties and presence in several natural products, the difficulty in …

Spiroindolines and spiroindoles are an important class of spirocyclic compounds present in
a wide range of pharmaceuticals and biologically important natural alkaloids. Various …

The catalytic enantioselective assembly of spirocyclic molecules featuring a spiro quaternary
carbon stereocenter is currently of great interest because such privileged 3D structures are …

We describe a fully stereodivergent synthesis of a range of α, α-disubstituted α-amino acids
via an Ir/Cu-catalyzed α-allylation of readily available imine esters. The introduction of a Cu …

We report stereodivergent allylic substitution reactions of allylic esters with prochiral
enolates derived from azaaryl acetamides and acetates to form products from addition of the …

Conspectus The Pictet–Spengler reaction is a fundamental named reaction in organic
chemistry, and it is the most straightforward method for the synthesis of tetrahydro-β …
