trans-1,2-Diaminocyclohexane functionalized mesoporous silica was applied as an ideal catalyst for asymmetric Michael addition of various nitroalkane derivatives. Short channels and plugs in the pore structure offered chiral enhancement in Michael addition.
Chiral γ-aminobutyric acid (GABA) derivatives are the normal inhibitory neurotransmitters in the mammalian central nervous system. In this paper, enantiopure GABA derivatives 6 were synthesized via reduction/cyclization/hydrolysis cascade reactions from the highly enantioselective β-aryl-γnitroalkanes Michael adducts 4, which was obtained from asymmetric Michael addition of S, S’-diphenyldithio...
