Chiral moieties were connected to the heteroatom-bridged calix-triazin scaffold by reactions of (S)- or (R)-(+)-1-(1-Naphthyl)ethylamine with tetraazacalix[4]arene[2]triazine. To utilize the catalytic activity of the chiral catalysts, diketones reacted with a wide variety of trans-beta-nitrostyrenes in Toluene, respectively, obtaining the Michael products in excellent yields and enantiomeric excesses (up to 96% yield and 99% ee).
