3,3‘-Bimorpholine Derivatives as a New Class of Organocatalysts for Asymmetric Michael Addition
TL;DR: New N-alkyl-3,3'-bimorpholine derivatives (iPBM) were revealed to be efficient organocatalysts for the asymmetric direct Michael addition of aldehydes to nitroolefins and a vinyl sulfone, with good to high levels of diastereo- and enantioselectivity.
Journal ArticleDOI
Synthesis and Characterisation of Chiral Triazole-Based Halogen-Bond Donors: Halogen Bonds in the Solid State and in Solution.
TL;DR: A general platform for the synthesis of various chiral halogen-bond (XB) donors based on the triazole core and the characterisation of factors that influence the strength of the halogen bond in the solid state and in solution are reported.
Journal ArticleDOI
Halo-1,2,3-triazolium Salts as Halogen Bond Donors for the Activation of Imines in Dihydropyridinone Synthesis
TL;DR: The catalytic properties of substituted enantiomerically pure halo-triazolium salts were explored in the reaction between an imine and Danishefsky's diene leading to the formation of dihydropyridinone, finding that impurities in the diene affected the rate of the reaction.
Journal ArticleDOI
A Novel Diastereoselective Multicomponent Cascade Reaction
TL;DR: A novel multicomponent cascade reaction led to the formation of a strained 3-azabicyclo[3.2.0]heptane derivative 4 which was reduced in a one-pot procedure to a stable alcohol 6 and obtained azabicyCLoheptanes, which are important pharmacophores.
Journal ArticleDOI
Calcium Hydroxyapatites as Efficient Catalysts for the Michael C–C Bond Formation

TL;DR: In this paper, a mechanism based on the basic properties of the calcium hydroxyapatite surfaces is proposed to explain their ability to catalyze the Michael reaction, which leads to the expected addition products.
