1-Lithio-1,3-dienes: Useful Building Blocks for Cyclic Compounds
Z. Xi
[Full Text PDF(J-STAGE)] Free Access Article
The application of substituted 1-lithio-1,3-dienes as building blocks for the preparation of cyclic compounds and linear compounds are briefly summarized. Results have revealed that the essential factor which makes 1-lithio-1,3-diene derivatives useful and unique as building blocks is the intra-cooperation between the alkenyllithium moiety and the butadienyl skeleton.

Development of 2,2′-Iminodiethanol Selective Production Process Using Shape-Selective Pentasil-Type Zeolite Catalyst
H. Tsuneki,* M. Kirishiki, and T. Oku
[Full Text PDF(J-STAGE)] Free Access Article
 |
The reaction of ethanolamines formation is a typical consecutive reaction, and therefore, 2,2′-iminodiethanol cannot be produced with high selectivity. A catalytic 2,2′-iminodiethanol selective production process was developed using a pentasil-type zeolite catalyst modified with a rare earth element and a binderless molded zeolite catalyst suitable for a fixed-bed reactor.

[Full Text PDF(J-STAGE)] [Supporting Information] Free Access Article
Schizophyllan (SPG) could form a complex with antisense oligonucleotides (AS ODN). When importin-β, a nuclear transport protein was bound to SPG (through a streptavidin–biotin interaction), the complex was transported into nucleus and inhibited telomerase.

Spontaneous Appearance of Chirally Asymmetric Steady States in an Oregonator-Based Reaction Model
K. Iwamoto
[Full Text PDF(J-STAGE)]
 |
A chiral symmetry-breaking reaction model was constructed based on the Oregonator model. Its symmetry-breaking transition results in the dominance of one enantiomer, and the disappearance of the other. Depending on the parameter values, an asymmetric steady state, symmetric steady state, or oscillatory behavior with either the same or different amplitudes is exhibited.

[Full Text PDF(J-STAGE)] [Supporting Information]
 |
The dipole moments of the ground- and excited-states of 1,4-naphthoquinone (1) and its derivatives were determined experimentally. The dipole moments of the excited-states of compounds 1–10 were larger than those of the ground-state. We examined also the results theoretically by using the DFT and CIS calculations.

Multibaric–Multithermal Molecular Dynamics Simulation of Alanine Dipeptide in Explicit Water
H. Okumura* and Y. Okamoto
[Full Text PDF(J-STAGE)]
The multibaric–multithermal algorithm samples much wider configurational space than the conventional isobaric–isothermal simulation. We performed a multibaric–multithermal molecular dynamics simulation of an alanine dipeptide in explicit water. Our results are in good agreement with those from Raman spectroscopy.

[Full Text PDF(J-STAGE)]
 |
The 2,6-naphthalenedicarboxylate ion included within the cavity of 3A,6A-anhydro-β-cyclodextrin caused the 1H NMR signals of the host to shift in different directions, depending on the positions of glucose units, indicating that the molecular rotation of guest is retarded within the deformed cavity of host.

Energy-transfer rates and crystal structures of rac-[Co(en)3]·rac-[Tb(dpa)3] double complex crystals (en = ethylenediamine, dpa = 2,6-pyridinedicarboxylate) and Δ-[Co(en)3]·rac-[Tb(dpa)3] were determined. The emission decay of former was fit to a single-exponential curve and the latter was fit to double exponential curve, due to different energy-transfer rates between Δ/Λ-[Tb(dpa)3]3−.

A ternary system consisting of anthracene-2,6-disulfonic acid, amines and guests was fabricated. Molecular information of the guest appears to be transcribed into a novel zigzag arrangement of anthracene moieties with assistance of (rac)-s-butylamine.
