Carbohydrate-Based Azacrown Ethers in Asymmetric Syntheses
نویسندگان
چکیده
Carbohydrate-based crown ethers represent a special group of chiral phase transfer catalysts. Several derivatives these macrocycles have been synthesized in our research group. Among compounds, monoaza-15-crown-5 lariat proved to be effective and enantioselective catalysts certain reactions. Those azacrown incorporating various carbohydrate moieties the macrocyclic structure are reviewed, which generated asymmetric induction reactions, such as Michael addition, epoxidation enones, Darzens condensation Michael-initiated ring-closure (MIRC) reaction. Effects on catalytic activity structural changes focus.

Novel Spin Labeled Azacrown Ethers
The ability of crown ethers [1—4] and cryptands [5—7] to selectively complex ions and neutral molecules has been the subject of extensive studies over the past two decades. One of the most impor tant problems under investigation was the transport of ionic species through membranes in biological sys tems [8 ]. Of several transport mechanisms proposed and demonstrated in natural and artificial ...

متن کاملOrganocatalytic asymmetric assembly reactions for the syntheses of carbohydrate derivatives by intermolecular Michael-Henry reactions.
Given the significance of carbohydrates in life, medicine, and industry, the development of simple and efficient de novo methods to synthesize carbohydrates are highly desirable. Organocatalytic asymmetric assembly reactions are powerful tools to rapidly construct molecules with stereochemical complexity from simple precursors. Here, we present a simple and robust methodology for the asymmetric...
متن کاملBifunctional transition metal-based molecular catalysts for asymmetric syntheses.
The discovery and development of conceptually new chiral bifunctional transition metal-based catalysts for asymmetric reactions is described. The chiral bifunctional Ru catalyst was originally developed for asymmetric transfer hydrogenation of ketones and imines and is now successfully applicable to enantioselective C-C bond formation reaction with a wide scope and high practicability. The depr...
