Special Issue Information

Dear Colleagues,

In biological systems, the two enantiomers, in many cases, have a different response. Thus, most of the new drugs reaching the market today are single enantiomers, rather than the racemic mixtures. In addition, nonracemic molecules also contribute to the creation of advanced materials. The synthesis of chiral organic compounds in a highly enantioselective manner is therefore of great importance. In the earliest stages of development, the creation of the chiral center is made possible thanks to chiral substrate, auxiliary, or stoichiometric amounts of chiral reagents. Since the discovery of homogeneous catalytic asymmetric hydrogenation reactions, a variety of highly efficient catalytic asymmetric reactions have been developed so far and research in asymmetric catalysis achieved prominence in both academic and industrial laboratories. Although some of asymmetric catalyses have reached a high level of selectivity and efficiency, interest in further improvements continues to grow period. This special issue of Molecules will highlight all areas of current and future interest, reflecting the tremendous expansion in the scope of the asymmetric catalysis.

I strongly encourage authors to submit their work to this special issue of Molecules.

Title: Catalytic Asymmetric Reactions Using Chiral Imidazoline- or Imidazolidine-metal Complexes.
Author: Takayoshi Arai
Affiliation: Department of Chemistry, Graduate School of Science, Chiba University Inage, Chiba 263-8522, Japan; E-Mail: tarai@faculty.chiba-u.jp
Abstract: We have succeeded to develop a series of chiral imidzoline- or imidazolidine- consisting ligands for metal-catalyzed reactions. For examples, imidazoline-aminophenol-Cu complex can catalyze the asymmetric Henry reaction and Friedel-Crafts reaction. The newly developed chiral pyridine bis(imidazolidine)-Cu complex becomes quite efficient catalyst for the endo-selective [3+2]-cyclization of iminoesters and nitroalkenes. The resent advances of the metal-catalyzed reactions will be presented.

Title: Chiral Aminophosphine-Catalyzed Asymmetric Double-Michael Reaction for The Synthesis of Enantioenriched Indolines
Authors: San N. Khong and Ohyun Kwon

Abstract: The bisphosphine-catalyzed double-Michael addition of dinucleophiles to electron-deficient acetylenes is an efficient process for the synthesis of a multitude of nitrogen-containing heterocycles. Since the heterocycles thus obtained contain at least one stereogenic center, the double-Michael reaction can be even more useful if an asymmetric variant of the reaction can be developed. Since aminophosphines can also facilitate the double-Michael reaction and chiral amines are more readily available in nature and through synthesis, several new chiral aminophosphines were prepared. When employed in the asymmetric double-Michael reaction of ortho-tosylamidophenyl malonate to activated acetylenes, the chiral aminophosphines produced excellent yields of indolines with moderate asymmetric induction.

Abstract: An efficient kinetic resolution of racemic secondary propargylic alcohols with achiral carboxylic acids using pivalic anhydride in the presence of (R)-benzotetramisole ((R)-BTM) was achieved.  Several useful synthetic intermediates of natural products were successfully produced by this new effective protocol.

Abstract: Cinchona alkaloid dimers were easily prepared by variousmethods. Quinuclidine nitrogen of cinchona alkaloid can be easilyquartanarized by halide. When dihalide was allowed to react with thecinchona alkaloid dimer, quaternarization polymerization occurs to givethe novel type of the chiral polymer. The catalytic activity of thepolymeric chiral organocatalyst was investigated.
