This communication describes a convenient route to optically active propylene carbonate by catalytic kinetic resolution process resulting from the coupling reaction of CO2 and racemic epoxides using simple chiral SalenCo(III)/quaternary ammonium halide catalyst systems.
A highly efficient asymmetric arylation of cyclic <i>N</i>-sulfonyl aldimines with arylboronic acids catalyzed by a rhodium/ sulfur–olefin ligand complex under mild conditions is described. wide range 4-aryl-3,4-dihydro-1,2,3-benzoxathiazine 2,2-dioxides were obtained in extremely high yields (93–99%) and enantiomeric purities (97–99% ee).
Abstract We report the helicoselective and convergent construction of indolohelicenoids with excellent efficiency stereocontrol. This reaction proceeds through a chiral‐phosphoric‐acid‐catalyzed enantioselective cycloaddition eliminative aromatization sequence, which can be finely controlled by adjusting temperature. Mechanistic studies reveal that chiral phosphoric acid cooperatively serves as both bifunctional Brønsted catalyst, enabling one‐pot central‐to‐helical chirality conversion....
There are three versions of distributional chaos, namely DC1, DC2 and DC3. By using an example constant-length substitution system, we show that DC3 need not imply Li–Yorke chaos. (In this paper, chaos means the existence uncountable scrambled set corresponding type, while existing only deals with a single pair points.)
It is known that in a compact dynamical system, the whole space can be Li–Yorke scrambled set, but this does not hold for distributional chaos. In paper we prove complement of distributionally set must an infinite set. Then give example uncountable dense invariant open extremal which countable This presents one kind "largest" (from topological point view) system. Moreover, construct closed
We study the relationship between DC3 pairs and set of discontinuities in distribution function. also check relations for a continuous map its higher iterates.
