Studies on Koenigs-Knorr Glycosidations.

Koenigs-Knorr synthesis of cycloalkyl glycosides.

Cadmium carbonate was found to be a useful promoter in the Koenigs-Knorr synthesis of 2-(4-methoxybenzyl)cyclohexyl-beta-D-glycopyranosides. Using this promoter model glucoside and galactoside derivatives of cyclic (i.e., secondary) alcohols were synthesized in 50-60 % overall yields. Diastereoisomeric mixtures of products were obtained in these syntheses, which started from racemic isomers of ...

12 Objectual practice Karin Knorr

In this paper, I want to develop some concepts designed to capture the affective and relational undergirding ofpractice in areas where practice is creativc and constructive. Current conceptions of practice emphasize the habitual and mle-governed features of practice. Though much debate surrounds the exact specification of the relevant mies and habits (see most authors seem to agree that practic...

Mean Growth of Koenigs Eigenfunctions

In 1884, G. Koenigs solved Schroeder’s functional equationf ◦ φ = λf in the following context: φ is a given holomorphic function mapping the openunit disk U into itself and fixing a point a ∈ U , f is holomorphic on U , and λis a complex scalar. Koenigs showed that if 0 <|φ′(a)| < 1, then Schroeder’sequation for φ has a unique holomorphic solution σ satisfyingσ ◦ φ =...

Geometric discretization of the Koenigs nets

We introduce the Koenigs lattice, which is a new integrable reduction of the quadrilateral lattice (discrete conjugate net) and provides natural integrable discrete analogue of the Koenigs net. We construct the Darboux-type transformation of the Koenigs lattice and we show permutability of superpositions of such transformations, thus proving integrability of the Koenigs lattice. We also investi...
