Carbon-carbon bond fragmentation in aminoalcohol radical cations. Kinetics, thermodynamic correlations, and mechanism
Burton, Richard D.,Bartberger, Michael D.,Zhang, Yin,Eyler, John R.,Schanze, Kirk S.
, p. 5655 - 5664 (1996)
A detailed study of the kinetics, thermodynamics and mechansim of carbon-carbon bond fragmentation in a series of aminoalcohol radical cations is presented. The compounds that provide the basis for this investigation are derived from the parent structure,
Thieme chemistry journal awardees-where are they now? bifunctional organocatalysis with N-Formyl-l-proline: A novel approach to epoxide ring opening and sulfide oxidation
Wei, Shengwei,Stingl, Kerstin A.,Wei?, Katharina M.,Tsogoeva, Svetlana B.
experimental part, p. 707 - 711 (2010/06/13)
A conceptually distinct approach to the aminolysis of 1,2-epoxides, which involves Lewis base-Br?nsted acid catalysis employing N-formyl-l-proline as an easily accessible bifunctional organocatalyst and water as a solvent is presented. The potential of N-formyl-l-proline as organocatalyst for the sulfide oxidation reaction using aqueous hydrogen peroxide as environmentally benign and readily available oxidant is also demonstrated. Good to high yields are achieved for both reactions. Georg Thieme Verlag Stuttgart ? New York.

supporting information; experimental part, p. 385 - 390 (2009/04/08)
The catalytic asymmetric ring opening of meso-epoxides with aromatic amines was achieved using a new proline-based N,N′-dioxide-indium tris(triflate) complex in high yields (up to 99%) with excellent enantioselectivities (up to 99% ee) under mild conditio

Aminolytic kinetic resolution (AKR) of trans-stilbene oxide and trans-β-methyl styrene oxide proceeded smoothly under microwave irradiation using chiral dimeric and polymeric Cr(III) salen complexes as efficient catalysts, giving regio-, diastereo-, and enantioselective anti-β-amino alcohols in high yields (49%) and chiral purity (ee up to 94%) in case of 4-methylaniline within 2 min. The kinetic resolution system is approximately five times faster than traditional oil bath heating at 70°C and 420 times faster than the reaction conducted at room temperature with concomitant recovery of respective chirally enriched epoxides (ee, 92%) in excellent yields (up to 48%). The catalyst 1 worked well in terms of enantioselectivity than the catalyst 2, but both the catalysts were easily recovered and reused five times with the retention of its efficiency.
