Stereoselective alkylations and rearrangements of chiral phosphonic and phosphinic acid derivatives
… effect the phosphorus analogues of the carbonyl-Curtius rearrangement. These studies showed that carbon migration in the phosphinoyl-Curtius rearrangement proceeds with 99% net retention of configuration while the migration in the first example of the phosphonoyl-Curtius rearrangement occurs with …

Syntax of the Simple Cases and of the Cases with Prepostionsions in Curtius History of Alexander Book III
… and of the cases with prepositions in Quintus Curtius’ History of Alexander, Book III. The text used is that of Edmund Heidicke in the Loeb Classical Library Series (1946). Since this study deals only with Book III, in citations of the text the book number is omitted and only the section and …

The Synax of the Simple Cases and the Cases with Prepostions in Quintus Curtius' History of Alexander, Book VI
… and of the cases with prepositions in Quintus Curtius’ History of Alexander, Book VI. This study attempts to ascertain any divergencies from the Classical norm, which might demonstrate Curtius’ syntax to be characteristic of a later period.</p>

The Syntax of the Finite Forms and the nominal Forms fo the Verb in Quintus Curtius'"History of Alexander, Bk. IX"
… and the nominal forms of the verb in Quintus Curtius' History of Alexander, Book IX, and to note the author’s conformity with or departure from classical usage. In using the chronological label, 'classical', I have adopted the following chronological scheme where a chronological label is …

Synthesis of Cylindricine C and its Stereoisomers
… ester. Key steps in our synthesis involve a Curtius rearrangement to install the nitrogen at the quaternary center and an electrophilic cyclisation to construct the tricyclic core. Desulfonylation and reduction of the resulting enaminone double bond moiety yielded 2,13-di-epi-Cylindricine C …

Aerosol-Schwefelsäure in der Atmosphäre und im Nachlauf von Düsenflugzeugen: Entwicklung und Einsatz einer neuartigen, flugzeuggetragenen Massenspektrometersonde
Ein neuartiges, flugzeuggetragenes Instrument, genannt 'VACA' (Volatile Aerosol Component Analyzer), zur quantitativen Bestimmung von Aerosol-Schwefelsäure (H2SO4(ae)) wurde entwickelt. Die VACA-Methode basiert auf dem Verdampfen von Aerosolteilchen mit anschließendem Nachweis der gasförmigen H2SO4 …

The Chemistry of Aroyl Azides in Piperidine- and Steroid-Separated Bichromophoric System: Photoinduced Long-Distance Intramolecular Electron Transfer Reactions
… of these compounds gives isocyanate by the photo-Curtius rearrangement and nitrene by loss of nitrogen. Light absorbed by the aryl amine donor chromophores initiates a through-bond electron-transfer reaction to form high energy, charge-separated intermediate states. The aryl amine radical cations …

Enantioselective synthesis using bromoacetals.
… into the corresponding Boc amide via a modified Curtius rearrangement is described.Possible further uses of dimethyl tartrate bromoacetals leading to the synthesis of highly functionalised lactones, lactols, epoxides, chiral diacids, diamines, chiral ligands, resolving agents etc are also …

Synthetic Studies on Tunicamycin Towards the Discovery of Antimetastatic Agents
… segments are assembled in a one-pot Büchner-Curtius-Schlotterbeck reaction in a wet solvent system. A series of DPAGT1 inhibitors can be synthesized in 11-12 chemical steps from the commercially available starting material with high overall yields. The current lead TN-Cy-TBPA displays …

New methodology for the synthesis of chiral, non-racemic a-tertiary amine centres: application to the synthesis of the marine alkaloid lepadiformine
… second section. This was achieved via a modified Curtius rearrangement protocol performed on quaternary carboxylic acids, in turn obtained from a chemoselective cleavage of a PMB ester malonate-auxiliary system. The ATA products were obtained in high yields and with retention of stereoselectivity, …
