Abstract: A sprayer includes a spray gun and a hopper. An air source provides compressed air to the sprayer to both eject fluid from the spray gun as a spray and to pressurize the hopper. The spray gun includes passages for providing compressed air to the nozzle for spraying and to the hopper for pressurizing the hopper. The spray gun further includes a relief valve for venting pressurized air from the hopper. The hopper receives the compressed air through a port in the hopper, and the compressed air assists the flow of material out of the hopper and into the spray gun.

Abstract: The present invention relates to a process for preparing substituted thiazolyl-amino pyrimidinyl piperazines, which are capable of inhibiting, modulating and/or regulating signal transduction of both receptor-type and non-receptor type tyrosine kinases.

Abstract: This invention provides methods for performing combined asymmetric amplification (e.g., asymmetric PCR amplification) and detection of nucleic acid targets using molecular beacons to detect the products. Methods using a polymerase having reduced or eliminated 5′ to 3′ nuclease activity are provided, as are methods using nuclease-resistant molecular beacons. Asymmetric amplifications using nuclease-free polymerase or nuclease-resistant molecular beacons provide dramatic improvements in signal intensity detected as a result of molecular beacon binding to a target nucleic acid, e.g., during asymmetric PCR. Attendant compositions, systems, devices and kits are also features of the invention.

Abstract: A process for preparing a &bgr;-hydroxy carbamate product is disclosed. The process comprises reacting an olefin compound containing at least one carbon-carbon double bond with a carbamate in an aqueous solvent and in the presence of a base, an osmium catalyst, a co-oxidant selected from a halohydantoin, a haloisocyanuric acid, and an alkali metal salt of a haloisocyanuric acid, and optionally an asymmetric ligand, to form a reaction mixture containing the &bgr;-hydroxy carbamate product. The process optionally further comprises treating the &bgr;-hydroxy carbamate product with additional base to form an oxazolidinone. The oxazolidinones are useful as chiral auxiliary agents and as intermediates for the formation of pharmaceutically active substances such as alpha 1 a adrenergic receptor antagonists. A process for preparing nitrogen-functionalized derivatives of the oxazolidinones is also disclosed.

Abstract: Indoles of structural formula (III): ##STR1## are synthesized by the palladium-catalyzed coupling/ring closure of a 2-halo or 2-trifluoromethylsulfonyloxy aniline and an alkyl ketone derivative. The process is particularly useful to form indoles containing acid-labile substituents such as triazole, acetyl, ketal, cyano, and carbamate, or indoles having a facile leaving group in the benzyl position. The advantages of the present process are that it does not require the use of triphenyl phosphine or tetrabutyl ammonium chloride or lithium chloride.
