When chiral compounds with low enantiomeric excess (ee, R:S=m:n) were absorbed into the void of the crystalline sponge (CS), enantiomerically pure [(R)m(S)n] chiral composites were formed, changing the centrosymmetric space group into non-centrosymme

The highly enantioselective cyclization of 3-alkenylindole via C–H activation has been established using Pd(OCOCF3)2 in conjunction with the chiral spiro bis(isoxazoline) ligand (SPRIX). The presence of an N-allyl substituent on the substrate has a

Determination of the absolute configuration of chiral tetra-substituted carbon centers is one of the most taxing steps in the enantioselective construction of this structural motif in asymmetric synthesis. Here, we demonstrate that the crystalline sp

Lanthanide contraction was used for helicity fine-tuning and helix winding control of single-helical tetranuclear complexes LZn3Ln (Ln = La–Lu); heavier lanthanides formed a tighter helix with a higher M/P ratio and gave a more abundant partially-c

Helicity of single-helical metal complexes, [L1Zn3La]3+ and [L2Zn2La]3+, was dynamically controlled by coordination of chiral carboxylate ions such as mandelate ion. Spectroscopic investigation indicated that two chiral carboxylate ions contribute to

Development of artificial helical molecules that can undergo responsive helicity inversion has been a challenging research target in functional molecular chemistry. However, most reported helicity inversions are based on a single-mode transition, i.e

Acyclic oligooxime ligands (H8L4 and H10L5) that have four or five N2O2 coordinating moieties (salamo moieties) were synthesised in order to obtain single-helical metal complexes with a greater number of winding turns. When the complexation of the te

Helicity of a single-helical oligooxime complex [(L)Zn3La]3+ was controlled efficiently by coordination with various kinds of α-amino acids. The helicity depends on the residues of the amino acids....

In biological systems, there are many signal transduction cascades in which a chemical signal is transferred as a series of chemical events. Such successive reaction systems are advantageous because the efficiency of the functions can be finely contr
