• Improvement of Photocatalytic Activity and Product Selectivity by Cadmium Metal Deposited<i>in situ</i>on Suspended Cadmium(II) Sulfide Particles

  Effect of annealing of commercial crystalline CdS powders on their photocatalytic activity and product selectivity was investigated for stereoselective diamino-N-cyclization of 2,6-diaminopimelic acid operated in a deaerated aqueous solution. Surface analyses revealed the formation of sulfur vacancy, which promotes the photoinduced cadmium metal (Cd0) deposition. The Cd0, detected by reduction of methylviologen, may act as a reduction site for photoexcited electrons.

• Synthesis of a key intermediate in the diaminopimelate pathway to L-Lysine: 2,3,4,5-tetrahydrodipicolinic acid

  2,3,4,5-Tetrahydrodipicolinic acid (3) is a key intermediate in the diaminopimelate (DAP) pathway to L-lysine (7). It was synthesized as the stable racemic potassium salt (25) from dipicolinic acid (14) by esterification, hydrogenation to the cis-diester (17), followed by elimination of p-toluenesuifinic acid from the N-toluenesulfonyl derivative (24) of dimethyl cis-piperidine-2,6-dicarboxylate with concomitant cleavage of the ester groups. (+/-)-2,3,4,5-Tetrahydrodipicolinic acid is unstable in neutral or acidic solution, and in basic solution it exists in equilibrium with the corresponding enamine (27) and 2-oxo-6-aminoadipate (26).

  Photoirradiation at wavelength >300 nm onto a deaerated aqueous suspension of cadmium(II) sulfide (CdS) particles in an aqueous solution of a mixture of stereo isomers of 2,6-diaminopimelic acid (DAP) produced piperidine-2,6-dicarboxylic acid (PDC). Both yield and trans/cis ratio of PDC markedly depended on the kind of CdS photocatalysts, its pre-treatment, and loading of fine platinum particles. A CdS photocatalyst prepared by heat-treatment at 1023 K in the presence of a small amount of air showed the highest yield and trans/cis ratio.
