A PTC-catalyzed diastereoselective Mannich reaction to access indanone-based α-amino acid derivatives.

We herein disclose a phase-transfer-catalyzed diastereoselective Mannich reaction between β,γ-alkynyl-α-ketimines and in situ generated 1-hydroxy isobenzofulvene anions from 2-alkylidene-1-indanones, enabling the formation of indanone-based α-amino acid derivatives with good results (up to 93% yield with >20 : 1 dr in...

Pd-Catalyzed Asymmetric Tandem Allylic Alkylation/Etherification: Enantioselective Access to Medium-Sized Oxa-spirocycles

Pd-catalyzed asymmetric tandem allylic substitution has proven to be a powerful strategy for constructing chiral rings; however, its application to chiral medium-sized spirocyclic systems remains undeveloped. Herein, we report a Pd-catalyzed asymmetric tandem allylic alkylation/etherification that enables efficient a...

Enantioselective (3+2) Cycloaddition–Rearrangement Strategy to Access Benzo[ d ]isothiazole‐Containing Polyheterocycles

Benzo[ d ]isothiazole motif has emerged as a privileged structure in medicinal chemistry and agricultural science. However, conventional synthetic methods are plagued by tedious multistep procedures, low atom economy and harsh reaction conditions, rendering the development of a facile and convenient approach for...
