new semigroup compactifications via the enveloping semigroups of associated flows
this thesis deals with the construction of some function algebras whose corresponding semigroup compactification are universal with respect to some properies of their enveloping semigroups. the special properties are of beigan a left zero, a left simple, a group, an inflation of the right zero, and an inflation of the rectangular band.
15 صفحه اولConcise access to indolizidine and pyrroloazepine skeleta via intramolecular Schmidt reactions of azido 1,3-diketones.
Readily prepared 2-alkyl-2-azidopropylcycloalkyl-1,3-diones undergo intramolecular Schmidt rearrangement with a range of hard Lewis acids, leading to indolizidinediones and pyrroloazepinediones. Chiral aluminium-based Lewis acids could also be used to mediate this symmetry-breaking transformation, but no significant asymmetric induction was observed.
متن کاملFlexible access to conformationally-locked bicyclic morpholines.
A preparatively accessible route to a series of conformationally-locked bicyclic morpholines has been developed. This flexible approach allows for diversification in order for a small array of lead-like scaffolds to be synthesised from readily available key building blocks.
متن کاملCytotoxicity of ruthenocene-containing β-diketones.
BACKGROUND Ferrocene-containing β-diketones and cisplatin, [(NH(3))(2)PtCl(2)], possess strong antineoplastic activity. No information is available regarding the anticancer activity of the corresponding ruthenocene complexes. This study examined the cytotoxicity of stable ruthenocene-containing β-diketones. The results were related to the cytotoxicity of cisplatin and the ease of ruthenium elec...
متن کاملConvenient access to bicyclic and tricyclic diazenes.
Heating the tosylhydrazone of an omega-alkenyl ketone or aldehyde to reflux in toluene in the presence of K(2)CO(3) delivered the bicyclic diazene. Irradiation of the diazene converted it to the cyclopropane. This appears to be a generally useful method for the construction of substituted cyclopentanes and cyclohexanes.
