Novel α,β-unsaturated imine derivatives of 3-aminopropylsilatrane

Novel highly functionalized and pharmacologically promising active silatranes equipped with an α,β-unsaturated imine group, Het(Ar)CH=C(SR)C(H)=N–, in the axial chain have been synthesized by the reaction of 3-aminopropylsilatrane and (Z)-2-alkylthio-3-(het)arylpropenals. The structures of these compounds were characterized by IR and ¹H, ¹³C, ¹⁵N, ²⁹Si, 1D and 2D NMR spectroscopy.
