Many congratulations Daniel and Kalipada for developing atroposelective phosphine/phosphine oxide redox catalysis for the isoquinoline-forming Staudinger–aza-Wittig reaction.
By the selective synthesis of atropisomeric sulfones with stereogenic C–S axes, catalyst control over threefold stereogenicity was achieved. Many congratulations Tanno, Stephan and Andreas!
Valeriia was recognized by the Camille and Henry Dreyfus Foundation for her ongoing PhD work. Many congratulations!
Very well done Zlatko: Alkene metathesis catalytically controls stereogenic axes by traceless arene formation.
Jianyang and Andreas successfully established the enantioselective synthesis of atropisomeric oQDMs (o-quinodimethanes) and were able to demonstrate their viability for highly stereoselective transformations. Many congratulations!
Many congratulations Valeriia for winning a best presentation prize at the Fall Meeting of the Swiss Chemical Society
Very well done Daniel: many congratulations. This stereodivergent approach allows the selective one-step synthesis of all four feasible atropisomeric two-axis systems.
Many congratulations Xingxing for establishing a stereoselective route to atropisomeric acridinium salts by a Friedel-Crafts electrocyclization of ortho-quinone methide iminiums by means of ion-pairing catalysis.

Many Congratulations. Tanno achieved an important milestone for our research: the catalyst-controlled thiiranation combined with stereospecific reductions to overcrowded alkenes, also in a fully stereodivergent manner.
