Chiral amination sulfoxide and preparation method thereof (by machine translation)

The invention belongs to the field of organic synthesis, and discloses chiral amination sulfoxide which has the structure of a general formula I. Wherein R is hydrogen or R1 And R2 Each independently selected from one of the following structures: hydrogen, alkyl, alkoxy, ester, trifluoromethyl, trifluoromethoxy, trifluoromethylthio. Halogens, alkynyl groups, alkenyl groups, amino groups, cyano groups, hydroxyl groups, aldehyde groups, carboxyl groups, nitro groups, amide groups, benzene rings, and bonded benzene ring fused rings to naphthalene; R3 Selected from the group consisting of phenyl, optionally substituted phenyl, aryl, heteroaryl, styryl, alkyl, haloalkyl and the like. The method comprises the following steps: forming a complex with a tert-butyl cyclopentadienyl metal iridium complex, forming a complex with the modified chiral proline, and activating C-H bond of enantioselective induced sulfoxide to obtain chiral sulphoxide. The synthetic method disclosed by the invention is high in yield and good in enantioselectivity, and the obtained amidated sulfoxide can be derivatized to obtain a chiral ligand.

NOVEL ADDUCTS OF SULFIDES AND 4-SUBSTITUTED 1,2,4-TRIAZOLINE-3,5-DIONES ( TAD )- A SIMILARITY OF TAD AND SINGLET OXYGEN ( 1O2 ) -

The 4-substituted 1,2,4-triazoline-3,5-diones( 2 ) afford with sulfides( 1 ) having acidic α-hydrogens the 1,4-disubstituted urazoles( 3 ).Reactivity of the triazoline-dione shows similarity in possible reaction modes with that of singlet oxygen.
