چکیده
In the crystal structure of the title compound, C(40)H(26)N(4), mol-ecules reside on crystallographic centers of inversion and are linked via C-H⋯N inter-actions about inversion centers into one-dimensional chains: longer C-H⋯π(arene) inter-actions complete the inter-molecular inter-actions.

The racemic title compound, C(54)H(38)O(2), consists of two C-linked penta-leno[1,2,3-ij]naphthalenone moieties, the crowded aryl ring substitution on the cyclo-pentane rings forcing the two segments to assume a conformation which has pseudo-twofold rotational symmetry, with a dihedral angle between the naphthalene substituent groups of 55.30 (8)°. In each segment, the two phenyl rings have dif...
متن کاملSynthesis and applicability of a photolabile 7,7-azi analogue of 3-sulfated taurine-conjugated bile salts.
For the identification of proteins involved in hepatobiliary transport, the photolabile derivative 7,7-ASLCT ((7,7-azi-3 alpha-sulfato-5 beta-cholan-24-oyl)-2'-aminoethanesulfonate) was synthesized. 7,7-ASLCT is taken up into liver and excreted into bile completely unmetabolized at a rate between the excretion rate of SLCT ((3 alpha-sulfato-5 beta-cholan-24-oyl)-2'- aminoethanesulfonate) and SC...
