- METHOD FOR PRODUCING ARYLSILANE COMPOUND CONTAINING HALOSILANE COMPOUND AS RAW MATERIAL
-
PROBLEM TO BE SOLVED: To provide a method for producing an arylsilane compound with low production cost. SOLUTION: A method for producing an arylsilane compound includes a reaction step for the cross-coupling reaction of a halosilane compound represented by general formula (A-1), (A-2), or (A-3) and an arylboronic acid pinacol ester in the presence of a nickel catalyst, a Lewis acid catalyst, and an organic base (R independently represent an aromatic hydrocarbon group, a heteroaromatic ring group, or a C1-20 hydrocarbon group; X independently represent a halogeno group or a trifluoromethanesulfonyloxy group).

- Synthesis of novel conjugated oligomers for second-order nonlinear optics: Incorporation of a central spacer as a conjugation modulator
-
A new series of second-order nonlinear optical chromophores has been synthesized that consists of a conjugated segment end-capped with an electron acceptor and an electron donor, respectively and a central spacer intended to modulate the electro-optical e

- Comparative study of new and known thienyl derivatives of ene-yne benzylamine as mammalian squalene epoxidase inhibitors
-
Analogs of the well-known squalene epoxidase inhibitor (SE) NB-598 (2) have been prepared and tested as cholesterol biosynthesis inhibitors in HepG2 cells. Among the compounds tested, the vinylthiophene analog 4 and the tertiary amide derivative of thiophene 8 emerged as potent human SE inhibitors and probably bind to the enzyme in a very similar manner as NB-598 (2). Surprisingly enough, compounds 4 and 8, contrary to NB-598, are poor inhibitors of rat SE, thus further demonstrating major differences between mammalian enzymes from different species.
