A novel class of platinum(II) complexes of pyridine sulfide derivatives of triazine was synthesized, characterized, and investigated using the human breast cancer cell line, MDA-MB-468. S-30 was one of the most potent derivatives of its class (IC(50)

A series of 1,n-dioxa[n](2,7)pyrenophanes (n = 7−12) with increasingly nonplanar pyrene moieties was synthesized by a 9−10 step sequence starting from 5-hydroxyisophthalic acid. The crystal structure of each member of this series was determined c

Through the use of a potentially removable tether, a heavily substituted 10b,10c-dimethyl-10b,10c-dihydropyrene (DMDHP), 20, was synthesized exclusively as the cis-isomer. It exists as the major component (20:1) in an equilibrium with its valence iso

The formation of p-tert-butylcalix[4]arene mono-, bis-, tris-, and tetrakistriflates 3, 2, 4, and 5, respectively, and their respective reactions, under typical Pd-catalyzed carbonylative, Suzuki-Miyaura coupling, or deoxygenation conditions are desc

Themostdistortedpyrenemoietyyetprepared (see picture) has been synthesized by the valence isomerization of a tethered [2.2]metacyclophane-1,9-diene to a 10b,10c-dihydropyrene and in situ dehydrogenation by 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (D

The major products from the exposure of tetracyclic keto-alcohol 1 to excess 1,4-naphthoquinone in the presence of acid were a hexacyclic quinone (6) and a heptacyclic dihydrobenzofuran derivative (8).

Calix[4]naphthalenes 11 and 12 in which hydroxyl groups are situated intraannularly can be oxidized with PTMATB and base to form the bis(spirodienone) 13, from 11, and bis(spirodienone) 20−21 and spirodienone 22, from 12. The prototype calix[4]naph

Maricite and sodium iron hydroxyphosphate (SIHP) are recently discovered iron(II) and iron(III) compounds that play a major role in phosphate “hideout” and corrosion in high-pressure boilers. This paper reports a novel method for synthesizing mar
