Considerable efforts have been undertaken by numerous groups in academia and industry over the past decade to expand the repertoire of coupling reagents in palladium(0)-catalyzed cross-coupling reactions. In particular, alkenyl phosphates and tosylates have proven their worth in various cross-coupling reactions, such as the Stille, Suzuki, 3] Negishi, Kumada, Sonogashira, b,e,f,5] Buchwald–Hart...

A series of new 1-aryl-4-(biarylmethylene)piperazines has been synthesized. These ligands are structurally related to SLV-313, a potential atypical antipsychotic having potent D2 receptor antagonist and 5-HT1A receptor agonist properties. Buchwald-Hartwig coupling reactions of 1-boc-piperazine with appropriate aryl halides and subsequent removal of the boc group rendered arylpiperazines. The re...
Mammalian platelets are small cell fragments with neither nu cleus nor microtubule organizing center. They circulate in the blood stream to survey vascular integrity. In their quiescent state, they have a flat, discoid morphology caused by a micro tubular ring structure, called the marginal band (MB), in the pe riphery of resting platelets (White and Rao, 1998). Endothelial damage will induc...
The solution of a problem arising in integrable systems [10] requires the asymptotics as α → ∞, with very small error, of the inverses and determinants of truncated Wiener-Hopf operators Wα(σ) acting on L (0, α), both in the regular case (where the Wiener-Hopf operator W (σ) on L2(R) is invertible) and in singular cases. This paper treats two cases where σ has simple Fisher-Hartwig singularitie...
