Chiral amplification based on enantioselective dual-phase distribution of a scalemic bisoxazolidine catalyst

A readily available bisoxazolidine ligand was found to catalyze the asymmetric alkylation of aldehydes with Et2Zn and less reactive Me2Zn, providing high yields and ee’s in both reactions. The bisoxazolidine-catalyzed alkylations and alkynylation of benzaldehyde show a positive nonlinear effect that cannot be accounted for by Kagan’s MLn model. The chiral amplification originates from selective phase distribution favoring enrichment of the major enantiomer of the scalemic catalyst in solution.

In conclusion, we affirm that quantitative kinetic descriptions of catalytic behavior continue to serve as an indispensable tool to navigate research efforts intended to model.

Photochemical studies on bicyclo[2.1.1]hexyl derivatives: Chemical behavior and asymmetric induction

The photochemical behavior of bicyclo[2.1.1]hexyl derivatives was investigated by irradiation with a 450 W medium-pressure mercury lamp in acetonitrile solution. The irradiation of methyl bicyclo[2.1.1]hexane-5- carbonylbenzoate (1a) led to both Norrish type II cyclization and cleavage products with a molar ratio of 1:2.2, whereas the irradiation of methyl 5-methylbicyclo[2.1.1]hexane-5-carbonylbenzoate (1b) afforded the only Norrish/Yang photocyclization compound as the sole product. Such results were illustrated by several geometric parameters for Norrish/Yang photoreaction as phi1, phi4 and beta obtained from the crystal structures. Furthermore, asymmetric photochemical studies using ionic chiral auxiliary technique were also conducted in the solid state. Bicyclo[2.1.1] hexanyl derivatives were synthesized and their photochemical behaviour was investigated in acetonitrile solution. Copyright

Conformationally constrained bis(oxazoline) derived chiral catalyst: A highly effective enantioselective Diels-Alder reaction

The reaction of cyclopentadiene with various bidentate dienophiles in the presence of 4-10 mol% of copper(II)-bis(oxazoline) complexes afforded excellent endo/exo selectivity as well as endo enantioselectivity (95-99% ee) and isolated yields.

Synthesis of chiral aminophosphines from chiral aminoalcohols via cyclic sulfamidates

(Chemical Equation Presented) Protic aminophosphines with multiple chiral centers were synthesized in good yields and high purity by the nucleophilic ring-opening of N-protected cyclic sulfamidates with metal phosphides, followed by hydrolysis and deprotection. This synthetic approach is clean, scalable, and high yielding. The method provides an efficient alternative route for the synthesis of chiral aminophosphines.

Chirality assignment of amines and amino alcohols based on circular dichroism induced by helix formation of a stereoregular poly((4- carboxyphenyl)acetylene) through acid-base complexation

An optically inactive polyacetylene, poly((4-carboxyphenyl)acetylene) (poly-l), exhibits an induced circular dichroism (ICD) in the UV-visible region upon complexation with chiral amines and amino alcohols in DMSO and in the film, the sign of which reflects the stereochemistry including bulkiness, type (primary, secondary, or tertiary), and absolute configuration of the amines. Therefore, the polyacetylene can be used as a novel probe for determining the chirality of amines. Most primary amines and amino alcohols of the same configuration gave the same sign for the induced Cotton effect; however, secondary and/or tertiary amines used in the present study tended to show Cotton effect signs opposite to those of the primary amines and amino alcohols of the same configuration. The magnitude of the ICD likely increases with an increase in the bulkiness of the chiral amines. The complexation dynamics during the formation of the helical structure of poly-1 with chiral amines were investigated on the basis of the spin-spin relaxation behavior and 1H NMR, CD, and optical rotatory dispersion (ORD) titrations. The complex formation of poly-1 with chiral amines such as 1-(l- naphthyl)ethylamine and 2-amino-l-propanol exhibits a positive nonlinear effect between the enantiomeric excess of the chiral amines and amino alcohols and the observed ellipticity of the Cotton effects. The excess enantiomer bound to poly-1 may induce an excess of a single-handed helix (rightor left-handed helix), which may result in a more intense ICD than that expected from the ee of the amine. Moreover, it was found that the coexistence of achiral amines such as l-aminoethanol also induced an excess of one helical sense of poly-1.
