Nickel-catalyzed decarbonylative polymerization of 5-alkynylphthalimides: A new methodology for the preparation of polyheterocycles
A nickel-catalyzed decarbonylative cycloaddition was developed, in which 5-alkynylphthalimides reacted to afford a new type of polyisoquinolone. It was demonstrated for the first time that decarbonylative cycloaddition can be an elementary process of polycondensation for the preparation of heterocyclic polymers.

Liquid-crystalline polymorphism of symmetrical azobananas: Bis(4-(4-alkylphenyl)azophenyl) 2-nitroisophtalates
In this paper we present a series of novel compounds, bis(4-(4-alkylphenyl) azophenyl) 2-nitroisophtalates, which exhibit nematic and banana-type liquidcrystalline phases. The alkyl chain length varies from 1 to 18 carbons. The first ten members of this series exhibit nematic phase. The last eleven compounds exhibit banana-type liquid crystalline phases. The propyl and pentyl derivatives have extra second type of banana mesophase. Copyright Taylor & Francis Group, LLC.

Therapeutic agent for osteoporosis and diazepine compound
A therapeutic agent for osteoporosis, comprising an azepine compound of the formula STR1 wherein each symbol is as defined in the specification, or a pharmaceutically acceptable salt thereof as an active ingredient, a method for treating osteoporosis comprising administering said compound and a use of said compound for the production of a therapeutic agent for osteoporosis. The compounds of the formula (I) have superior bone resorption-inhibitory activity and act to reduce the increased amount of calcium in blood serum, which is caused by bone resorption. Accordingly, these compounds are usable as pharmaceutical agents to effectively inhibit bone resorption, to prevent decrease of bone mass and to prevent or suppress the increase of calcium amount in blood serum which is caused by the progress of bone resorption, with regard to Paget's disease, hypercalcemia, osteoporosis and so on in which the progress of bone resorption is considered to be deeply associated with the symptom, and to the symptoms of progressing bone resorption (development into osteoporosis) along with inflammatory joint diseases such as rheumatoid arthritis.

LIQUID CRYSTALLINE PROPERTIES OF 4-CHLOROBENZYLIDENE-4-AKYLANILINES
A new group of Schiff bases containing a polar terminal group was synthesized: .The alkyl was changed from n=1 to n=12.Based on calorimetric (DSC) studies and on observations of textures the phase situation was characterized.

Study of the Influence of Molecular Length on the Characteristics of the Ordered Smectic Phase.
Study of DTA and X-rays of p-phenyl-benzylidene-p'-alkylanilines of mesomorphic phases demonstrates the predominant role of the aliphatic chain length. In effect, it governs the appearance of the different phases; the correlation between layers decreases for greater chain lengths. The nonlinear variations of SmB layer thickness for these compounds shows clearly the importance of steric effects coupled with the molecular length with respect to the dipolar effect.
