6,6′‐Substituent Effect of BINOL in Bis‐Titanium Chiral Lewis Acid Catalyzed 1,3‐Dipolar Cycloaddition of Nitrones.
TL;DR: By the accommodation of modified BINOLs as chiral ligands, enantioselectivities in the bis-titanium chiral Lewis acid catalyzed 1,3-dipolar cycloaddition of N-diphenylmethyl nitrones and methacrolein could be improved.

Synthesis of a Biphenyl‐Based Axially Chiral Amino Acid as a Highly Efficient Catalyst for the Direct Asymmetric Aldol Reaction.
TL;DR: A biphenyl-based axially chiral amino acid ( S- 2) has been designed and synthesized and found to be a more efficient catalyst than ( S )- 1 in the direct asymmetric aldol reaction of acetone with aldehydes.

Asymmetric Inverse‐Electron‐Demand 1,3‐Dipolar Cycloaddition of C,N‐Cyclic Azomethine Imines: An Umpolung Strategy.
TL;DR: In this article, it was shown that dicarboxylic acids exhibit high catalytic activity in the title reaction of dihydroisoquinoline derivatives with vinyl ether to give the cycloadducts exclusively as exo-isomers with excellent enantioselectivities.

Unusually stable silyl ketones with bowl-shaped tris(2,6-diphenylbenzyl)-silyl group for various nucleophilic attacks and α-deprotonation
TL;DR: In this paper, a bowl-shaped tris(2,6-diphenylbenzyl)silyl (TDS) group was successfully utilized as a highly effective shield of ketone carbonyls for various nucleophilic attacks and α-deprotonation.
