construction of various heterocyclic rings. The reactions of pyrylium or thiopyrylium salts, six-membered cationic heteroaromatics containing an oxygen or sulfur atom, with nitrogen-containing nucleophiles to afford a variety of nitrogen-containing heterocyclic compounds provide one of the most effective examples of the ring transformation. Sixmembered heterocycles such as pyridines, quinolines...
متن کاملParadoxical reactions to benzodiazepines.
Paradoxal reactions to benzodiazepines may be presented in different ways. In some persons, primarily older persons and children, especilally with coexisting somatic disorders, paradoxal reactions may be manifested as logoroic speech, unapropriate social behaviour, and psychomotor agitation. Although benzodiazepines lower levels of agression, few studies described that in some persons levels of...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولa new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
15 صفحه اولEasy access to Evans' oxazolidinones. Stereoselective synthesis and antibacterial activity of a new 2-oxazolidinone derivative.
An interesting new approach was developed for the synthesis of Evans' chiral auxiliaries with excellent yields. In turn, another new stereoselective and efficient strategy has also allowed for the preparation of a 2-oxazolidinone derivative in 34% overall yield from the Morita-Baylis-Hillman adduct. The antibacterial activity of this oxazolidinone was tested against Staphylococcus aureus strain...
