Summary: Without chiral induction, the emergence of homochirality from achiral molecules is accidental due to the ambiguity of the rationale. In this study, we propose a plausible solution: by forming a pair of interconverting cage conformers from achiral precursors, each conformer self-sorts into a homochiral crystal when their interconversion is hindered by intramolecular H-bonding. This self-assembly process is driven by a helical network of multivalent intermolecular interactions. Our findings provide insights for the rational design of homochirality emergence.

Summary: The study found that in the presence of lactic acid enantiomers, three-dimensional chiral 3d-4f heterometal-organic frameworks can be formed and spontaneously resolved from achiral ligands, while in the absence of lactic acid enantiomers, the reactants randomly generated both enantiopure crystals. The enantiopure lactic acid induced asymmetric resolution to achieve single chiral crystallization. DFT theoretical calculations showed that the absolute chiral resolution of the enantiomers is due to the difference in the interactions between the two enantiomeric units and the chiral inducer.

Summary: This article explores the observation of spontaneous mirror symmetry breaking and chiral amplification in stereoselective Mannich and aldol reactions under fully achiral initial conditions. By using DFT computation and numerical solution of kinetic rate equations, the authors provide a rigorous model for the aldol reaction without making any a priori assumptions. They explain the spontaneous mirror symmetry breaking in this system as a result of a supercritical pitchfork bifurcation, and suggest that similar processes in the primordial soup might explain the origin of biological homochirality. The results indicate that seemingly harmless chemical reactions can exhibit unexpected emergent behavior under appropriately chosen initial conditions.

Summary: The achiral compound DIO, which exhibits three nematic phases, has been studied in confinement under different surface conditions using polarizing microscopy and electro-optics. The high temperature N phase shows optical activity and linear electro-optic response, which can be attributed to its polar nature. Chiral domains are formed due to spontaneous symmetry breaking caused by saddle-splay elasticity, leading to the formation of helical domains with opposite chirality. This is the first observation of helical segregation in calamitic non-chiral molecules in the nematic phase. The ferronematic N-F shows strong polar azimuthal surface interaction energy, resulting in a homogeneous structure in planar aligned cells and a twisted structure in cells with antiparallel buffing. The observed agreement between experimental and simulated transmission spectra confirms the presence of twisted structures in antiparallel rubbed cells.
