Often, the next step is what could be called a Schiff base transfer: the PLP is transferred from the enzyme lysine to the nitrogen of the amino acid substrate. The imine is visible at approximately 4. Organic Chemistry, 6th ed. Lehninger Principles of Bio- chemistry; Worth Pub.
The imine itself is not only a versatile, useful elec- trophile in other reactions, but its synthesis, purification, and Chloroform-d is harmful to the central nervous system analysis involve organic chemistry techniques appropriate for if ingested or inhaled in high concentrations and may cause undergraduate students. Houk, K. Follow- ing the attack, condensation produces the electrophilic imine; This reaction is based on the procedure of Manhas et in this reaction, the ester group enhances the electrophilicity al. Specifically, they saw that NMR and GC—MS an imine of high purity and excellent yield after a reaction could be used together to obtain much more information time of one week under the conditions previously described.

While the GC—MS and 1H NMR The following week, the imine was isolated by vacuum spectra of the starting materials can be compared to predicted filtration followed by vacuum distillation. Based on your knowledge of the mechanism of acetal and ketal formation, you might expect that the next step would be attack by a second amine to form a compound with a carbon bound to two amine groups — the nitrogen version of a ketal. Hydrazones are used as part of the Wolff-Kishner reduction and will be discussed in more detail in another module.
