    Abstract
    A one-pot, three-component, Mannich reaction of electron-rich aromatic compounds with in situ prepared iminium salts in 5 M ethereal lithium perchlorate gives good yields of aminoalkylated products at room temperature. © 2001 Elsevier Science Ltd. All rights reserved  

    A simple one-pot three-component reaction for preparation of secondary amines and amino esters mediated by lithium perchlorate

    , Article Tetrahedron ; Volume 57, Issue 31 , 2001 , Pages 6829-6832 ; 00404020 (ISSN) Saidi, M. R ; Azizi, N ; Zali Boinee, H ; Sharif University of Technology

    Abstract
    The one-pot synthesis of several secondary amines and secondary amino esters are reported. Treatment of aldehydes (aliphatic or aromatic) with (trimethylsilyl)alkylamines, in the presence of 5 M lithium perchlorate in diethyl ether gives intermediate imines. Reaction of these intermediate imines with different nucleophiles and functionalized organozinc reagents, BrZnCH2COOR, produce a variety of secondary amines and N-alkyl- or N-arylamino esters in good yields. © 2001 Elsevier Science Ltd.
