We describe in this study the asymmetric synthesis of radioisotope (RI)-labeled selective glucocorticoid receptor modulator. This synthesis is based on optimization of the cinchona alkaloid catalyzed addition of 6-bromoindole to ethyl trifluoropyruva

Photoinduced charge-separation and charge-recombination processes of the three ferrocene−C60 dyads have been investigated by using laser flash photolysis methods. From molecular orbital calculations, the HOMO states are delocalized over the ferroce

The novel carborane–ferrocene conjugated dyads 1–3 and 6–8 were synthesized and their NLO properties were investigated. ortho-, meta-, and para-carboranes act as electron-withdrawing groups, and the para-carborane dyads 3 and 8 exhibited higher

Several novel types of cyclophanes were efficiently synthesized via an intermolecular palladium-catalyzed cross-benzannulation of cyclic enynes and diynes. These types of cyclophanes are not accessible through an intramolecular mode of the homo-benza

We report the high reactivity of electron-deficient enynes in the homo-benzannulation of conjugated enynes in the presence of Pd(PPh3)4. The introduction of electron-withdrawing groups enabled us to carry out the benzannulation of 1-substituted enyne

We report the high reactivity of alkoxycarbonyl- and cyanoenynes in the homo-benzannulation of conjugated enynes. The introduction of these electron-withdrawing groups enabled us to carry out the benzannulation of 1-substituted enynes as well as 1,2-

A series of novel exomethylene paracyclophanes was synthesized by the intramolecular benzannulation of conjugated enynes in the presence of tetrakis(triphenylphosphine)palladium(0). Detailed spectral studies revealed that the conformation of the exom

A series of novel fullerene–ferrocene derivatives has been synthesized and their NLO properties investigated. Ferrocene acts as a donor and fullerene as a good acceptor, leading to large hyperpolarizabilities, especially in the case of the compound
