Kinetically fast racemization of chiral substrates through an achiral intermediate and enantioselective functionalization of one of the enantiomeric substrates forms the basis of the dynamic kinetic resolution (DKR) of centrally chiral molecules. We report ...
Asymmetric synthesis of enantioenriched zigzag-type molecular belts featuring copper/H8-binaphthol-catalyzed kinetic resolution of a resorcinarene derivative and subsequent transformations was developed. The acquired rigid and C4-symmetric belt exhibited r ...
We report in this article a cascade reaction strategy for the synthesis of complex N-heterocyclic compounds with contiguous and tetrasubstituted stereogenic carbons. Under the sequential catalysis of a chiral binol–Ti complex and BF3, cyclopentanone-derive ...
We report herein a strategy to construct enantiopure inherently chiral macrocycles, ABCD-type heteracalix[4]-aromatics, through a catalytic enantioselective intramolecular C−N bond forming reaction. A chiral ligand-palladium complex was found to efficientl ...

Herein we report a two-directional cyclization strategy for the synthesis of highly strained depth- expanded oxygen-doped chiral molecular belts of the zigzag-type. From the easily accessible resorcin[4]arenes, an unprecedented cyclization cascade generati ...

We report herein an efficient cascade strategy for the rapid construction of a highly enantioenriched erythrinane core skeleton. Under the sequential catalysis of a chiral Cr(III)(salen)Cl and InCl3, cyclohexanone-derived tertiary enamides undergo an intra ...

Under the catalysis of PdBr2 and a chiral phosphoramidite ligand, the upper-rim mono (2-bromoaroyl)- substituted calix[4]arene derivatives underwent a facile enantioselective desymmetrization reaction to afford 9H-fluorene-embedded inherently chiral calixa ...
Here we report an organocatalytic double Ugi reaction combining the enantioselective process and ee enhancement in a single operation to afford the chiral Ugi products with very high ee values. Both bisisocyanides and bisanilines tethered by carbonate and ...
The small Stokes shift and weak emission in the solid state are two main shortcomings associated with the boron-dipyrromethene (BODIPY) family of dyes. This study presents the design, synthesis and luminescent properties of boron difluoro complexes of 2-ar ...
Pd(OAc)2-catalyzed intramolecular dehydrogenative cross-coupling reaction between tertiary enamides, which were derived from the condensation of 2-arylethylamines and methyl o-acetylbenzoate, and arenes enabled synthesis of 7,8-dihydro-5H-benzo[4,5]azepino ...
