  Chiral Arrangement of N-Ethyl-N-isopropylphenylglyoxylamide Molecule in Its Own Crystal and in an Inclusion Crystal with a Host Compound and Their Photoreactions in the Solid State That Give Optically Active β-Lactam Derivatives. X-ray Analytical and CD Spectral Studies

  摘要：

  N-Ethyl-N-isopropylphenylglyoxylamide (3c) forms chiral crystal in which its achiral molecules are arranged in a chiral form, and the chirality in the crystal was identified by measurement of the CD spectrum in Nujol mull. Generation of the chirality occurs by twisting of the CO-CO bond of 3c in the crystal. Photoirradiation of the chiral crystal of 3c in the solid state gave optically active beta-lactam derivative (4c) of 80% ee. By X-ray analysis, absolute configurations of the chiral crystal and 4c were elucidated. The achiral molecules of 3c are also arranged in chiral forms in inclusion complexes with chiral hosts such as (R,R)-(-)-trans-2,3-bis(hydroxydiphenylmethyl)-1,4-dioxaspiro[4.4]nonane (5a), (R,R)-(-)-trans-2,3-bis(hydroxydiphenylmethyl)-1,4-dioxaspiro[5.4]decane (5b), and their (S,S)-(+)-enantiomers, 6a and 6b, respectively. The crystal structure of a 1:1 inclusion complex of 3c with 5b (7b) was analyzed. Photoirradiation of 7b in the solid state gave (R)-(+)-4c of 85% ee. Photochemical conversions of some other derivatives of 3c to the corresponding beta-lactams were also studied. Interestingly, however, irradiation of the 1:1 inclusion complex of N,N-dimethylglyoxylamide (3a) with 5a, which had been prepared by mixing both components in the absence of solvent, gave (R)-(+)-beta-lactam (9a) of 45% ee, although the 1:1 complex that had been prepared by recrystallization of the components from toluene gave (S)-(-)-9a of 100% ee. Mixing of powdered chiral (-)-3c crystal with a 2:1 inclusion complex of 5b and MeOH gave a new 1:1 complex of 5b and chiral (+)-3c, The inversion of the chirality of 3c in the solid state was studied by continuous measurements of CD spectra in Nujol mulls.

• Achiral Molecules Move and Order Themselves in a Chiral Form in Host-Guest Inclusion Crystals

  When optically active host compound was mixed with achiral guest compound in the solid state, host-guest inclusion crystals were formed by molecular movement and the achiral molecules became arranged in a chiral form in the inclusion crystals. Mixing of powdered (+)-host crystals with powdered (−)-guest crystals which are formed by a chiral arrangement of achiral guest molecules gave inclusion crystals of the (+)-host and the (+)-guest molecules newly produced through an inversion of the (−)-guest molecules during the complexation in the solid state.

  当光学活性主化合物与非手性客体化合物在固态下混合时，通过分子运动形成了主-客体包晶，非手性分子在包晶中呈手性排列。将粉末状(+)-主晶与粉末状(-)-客晶混合，后者是由非手性客体分子的手性排列形成的，在固态络合过程中，通过(-)-客体分子的反转，产生了新的(+)-主晶和(+)-客体分子的包合物晶体。
