acids with 3-aryloxy-2-oxopropyl residues in position 1 were previously reported to be potent inhibitors of human cytosolic phospholipase A2α (cPLA2α). In continuation of our attempts to develop clinical active cPLA2α inhibitors, a series of structurally related indole-5-carboxylic acids with reduced lipophilicity was synthesized and tested for cPLA2α-inhibitory potency. Furthermore, the thermodynamic solubility
chiral alkyl group, synthesized by a palladium-catalyzed coupling reaction, provide a new series of liquid crystalline materials which form chiral smectic C (SmC*) phases exhibiting ferroelectric properties. Mesomorphic properties of the compounds composed of threearomaticrings is strongly affected by the position of an acetylenic linkage and the direction of an esterlinking unit.

Carbonylation of ( E )-2-(4-halobenzylidene)- p -menthan-3-ones, catalyzed by PdCl2(PPh3)2, gave a distereometric mixure of 4-[(1 R ,4 R )- and (1 R ,4 S )-3-oxo- p -menthan-2-ylidenemethyl]benzoicacids, whose reaction with phenols gave 1 R ,4 R diastereomers of the corresponding esters.

Liquid Crystalline Properties of 4-Alkoxyphenyl 4-Thiocyanatophenyl Terephthalates
This paper describes the preparation and thermal properties of a homologous series of 4-alkoxyphenyl 4-thiocyanatophenyl terephthalates. The homologous series shows nematic and smectic A phases commencing from the pentyloxy homolog. The smectic A phase is immiscible with the smectic A phase of polar liquid crystals having a terminal cyano group. Interestingly, the smectic B phase is also formed from the hexyloxy homolog, while the compound has a polar group at the terminal position.
本文介绍了 4-烷氧基苯基-4-硫氰基苯基对苯二甲酸盐同系物的制备方法和热性能。该同系物从戊氧基同系物开始出现向列和共晶 A 相。共晶 A 相与具有末端氰基的极性液晶的共晶 A 相互不相溶。有趣的是,B 相也是由己氧基同族体形成的,而化合物的末端位置有一个极性基团。
