DOI: 10.1016/j.tet.2021.132088

Abstract: Abstract The preparation of four novel ferrocenylphosphinamine ligands, possessing both planar and central chirality, is described. The absolute configuration of two of the ligands was confirmed by X-ray crystallographic analysis. The palladium complexes of these… read more here.

DOI: 10.1021/acs.jctc.2c01265

Abstract: Chirality is ubiquitous in nature, ranging from a DNA helix to a biological macromolecule, snail's shell, and even a galaxy. However, the precise control of chirality at the nanoscale is a challenge due to the… read more here.

DOI: 10.1021/acs.orglett.9b00277

Abstract: Planar chirality inversion of pillar[5]arenes bearing d- or l-alanine substituents on both rims was investigated upon addition of guest molecules having pyridinium or imidazole moieties and long alkyl chains. The d- and l-alanine-substituted pillar[5]arenes exhibited… read more here.

DOI: 10.1021/jacs.1c11699

Abstract: Chiral organometallic complexes have demonstrated many potential and practical applications. However, building metal-induced chirality for square-planar complexes still remains a big challenge, because their 2D planar molecular structures are usually superimposable on their mirror images.… read more here.

DOI: 10.1021/jacs.3c01019

Abstract: Chirality of host molecules can be induced and/or inverted by the guest molecules. However, the adapting chirality of hosts to the length of n-alkanes remains a great challenge because n-alkanes are neutral, achiral, and linear… read more here.

DOI: 10.1021/jacs.4c06308

Abstract: The strain-induced chirality of cyclophanes has attracted interest within the synthetic community. Herein, we report the synthesis of anilinocyclophanes derived from naturally occurring terpenes, such as citronellol, geraniol, and farnesol. The resulting cyclic oligoprenyl molecules… read more here.

DOI: 10.1039/d1sc00074h

Abstract: Regulating the chirality of macrocyclic host molecules and supramolecular assemblies is crucial because chirality often plays a role in governing the properties of these systems. Herein, we describe pillar[5]arene-based chiral nanotube formation via pre-regulation of… read more here.

DOI: 10.1039/d2cc05742e

Abstract: We synthesized planar chiral cyclophanes with multiple pairs of helical conformations that were generated by twisting at the interlayer. Three- and four-layer cyclophanes preferred a homochiral form with a single sense of twisting through intramolecular… read more here.

DOI: 10.1039/d2sc00952h

Abstract: Herein, we report the synthesis and planar chiral properties of a pair of water-soluble cationic pillar[5]arenes with stereogenic carbons. Interestingly, although units of the molecules were rotatable, only one planar chiral diastereomer existed in water… read more here.
