    Asymmetric Mannich-Type Reaction of a Chiral N -(tert -Butylsulfinyl) Ketimine with Imines: Application to the Synthesis of Chiral 1,3-Diamines

    EUROPEAN JOURNAL OF ORGANIC CHEMISTRY, Issue 13 2006
    Cui-Hua Zhao
    Abstract Deprotonation of the chiral N -(tert -butylsulfinyl) ketimine 1 followed by trapping with imines 2 afforded the ,-aminoimines 3 as the Mannich-type products in high diastereoselectivities (99:1 dr). As versatile synthons chiral ,-amino imines 3 could be transformed into enantiomeric ,-amino ketone and chiral syn - or anti -1,3-diamines with high diastereomeric excess by hydrolysis or reduction, respectively. Moreover, the nucleophilic addition of organometallicreagents to chiral ,-amino imines 3 could provide 1,1,3-trisubstituted 1,3-diamines with high diastereoselectivities.

    An Efficient Synthesis of Novel ,-Aminophosphonates Based on a Mannich-Type Reaction

    EUROPEAN JOURNAL OF ORGANIC CHEMISTRY, Issue 2 2005
    Nikolaus Risch
    Abstract Phosphonate-substituted iminium salt 2 was used in Mannich reactions with various nucleophiles to obtain novel ,-aminophosphonates. This straightforward and efficient methodology has a broad scope and provides highly functionalized Mannich bases (4 and 8). Furthermore, vinylic, aromatic and homoallylic ,-aminophosphonates (5, 10 and 12) were synthesized in good yields. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005) [source]

    Bromodimethylsulfonium Bromide Catalyzed Three-Component Mannich-Type Reactions

    EUROPEAN JOURNAL OF ORGANIC CHEMISTRY, Issue 5 2008
    Abu T. Khan
    Abstract Bromodimethylsulfonium bromide catalyzes Mannich-type reactions of a variety of aldimines, generated in situ from aldehydes and anilines, with enolizable ketones or diethyl malonate in three-component reactions to afford the corresponding ,-amino carbonyl compounds. The salient features of this protocol are: shorter reaction times, simplicity of the procedure, good to excellent yields, avoidance of aqueous workup and column-chromatographic separations, and high stereoselectivities.(© Wiley-VCH Verlag GmbH & Co.

    Ju Hee Lee
    Abstract The catalytic enantioselective electrophilic Mannich-type reaction promoted by chiral bifunctional organocatalysts is described. The treatment of ,-cyano ketones with N -Boc-aldimines under mild reaction conditions afforded the corresponding ,-amino-,-cyano ketones with excellent diastereoselectivities (up to syn/anti=100/0), and excellent enantioselectivities (up to 99% ee).
