Chiral iron complex catalyzed enantioselective oxidation of racemic benzoins.
An efficient, economic and environmentally friendly enantioselective oxidation of racemic benzoins (alpha-hydroxy ketones) catalyzed by a chiral iron complex has been developed using molecular oxygen as a terminal oxidant with good selectivity and excellent enantiomeric excess.

15 صفحه اولFeCl3-promoted alkylation of indoles by enamides.
An efficient iron-promoted alkylation of indoles with enamides has been accomplished under mild reaction conditions. The reaction proceeded with remarkable regioselectivity leading exclusively to substitution by indoles at α-position of enamides.
متن کاملOxidation of Benzoins with Pyridine N-oxide - SbC15 (1 : 1) Complexes+
When a mixture of a few benzoins and a pyridine N-oxide SbC15 (1 : 1) complex (Complex A) was boiled in nitromethane, the corresponding benzils were obtained in various yields dependent upon the kinds of substituents in each reactant. The yield of benzil becames higher by adding some tertiary amines. In this reaction, tribenzylamine is a good accelerator to promote it. When Complex A, 4-picolin...
متن کاملCatalytic Oxidation by Means of Complex Iron
The observation of Manchot? that sodium pentacyano-ammineferroate2 I absorbs oxygen has led Baudisch and his coworkers3 to study the catalytic action of this salt, as well as of its water analogue II, in the oxidation of pyrimidines and purines. The present authors have previously reported in this journal4 on the nature of the oxidation products obtained. In the present paper the problem is con...
