Paragraph 0053; 0056-0057, (2017/05/17)
The invention relates to a trandolapril intermediate preparation method which is as follows: reacting cyclohexene and chloramines-T as starting materials to obtain cyclohexane aziridine; reacting the cyclohexane aziridine with an allyl Grignard reagent to

The first example of direct reductive amination (DRA) of ketones with electron-deficient amines (EDA) such as Cbz-, Boc-, EtOCO-, Fmoc-, Bz-, ArSO2-, etc. protected amines have been achieved using catalytic Re2O7/NaPF6. Excellent chemoselectivities as well as diastereoselectivity (for 2-alkyl cyclohexanones) were obtained. The Royal Society of Chemistry 2013.
CYCLISATION DE N-TOSYL OXIRANES-PROPYLAMINES: SYNTHESE D'HETEROCYCLES AZOTES.
Nuhrich, A.,Moulines, J.
, p. 3075 - 3088 (2007/10/02)
The cyclisation of N-tosyl-oxiranepropylamines is accomplished in aqueous basic medium and in anhydrous acid medium as well.In most cases, this reaction occurs by a regiospecific 5-exo-tet. ring closure and affords N-tosyl-2-pyrrolidinemethanols in high y
Palladium-Catalyzed Cyclization of ω-Olefinic Tosamides. Synthesis of Nonaromatic Nitrogen Heterocycles
Hegedus, Louis S.,McKearin, James M.
, p. 2444 - 2451 (2007/10/02)
The cyclization of aliphatic amino olefins to nonaromatic nitrogen heterocycles nas been accomplished by conversion of the amine to the corresponding p-toluenesulfonamide, followed by Pd(II)-catalyzed intramolecular amination of the olefin.The resulting t
