Abstract: Mechanistic understanding of asymmetric induction plays a crucial role in designing new catalytic asymmetric reactions. Reported herein is atroposelective access to C-N axially chiral isoquinolones via rhodium-catalyzed C-H activation of N-alkoxy benzamides and annulation with… read more here.

Abstract: Silylation and desilylation are important functional group manipulations in solution-phase organic chemistry that are heavily used to protect/deprotect different functionalities. Herein, we disclose the first examples of the σ-bond metathesis of silylated alkynes with aromatic… read more here.
