摘要: Two potential chiral auxiliaries, N-(E)-enoyl(-)-bornane-10,2-sultams, were synthesized from (-)-bornane-10,2-sultams. The molecular crystal structures of the title compounds were determined by diffraction analysis. The crystal of C16O3SNH25 belongs to a rhombic system, the space group is P212121 with cell parameters: a=0.734 6(7) nm, b=1.142 7(3) nm, c=2.009 7(3) nm, β=90.00°, V=1.686 9 nm3, Z=4, Dc=1.250 g/cm3, μ=1.926 cm-1 and F(000)=672. The crystal of C15O3SNH23 belongs to a rhombic system, the space group is P212121 with cell parameters: a=0.738 2(2) nm, b=0.921 6(1) nm, c=2.280 9(8) nm, β=90.00°, V=1.551 7 nm3, Z=4, Dc=1.273 g/cm3, μ=2.504 cm-1 and F(000)=640. The structural characteristics with respect to the potential utility for the stereoselective Michael addition reaction of the N-enoyl group are discussed.
