9-BBN: An amino acid protecting group for functionalization of amino acid side chains in organic solvents.

9-Borabicyclononane (9-BBN) has been utilized to protect functionalized amino acids for potential chemoselective side chain manipulation. The 9-BBN group imparts organic solubility to otherwise hydrophilic molecules and is tolerant of a wide range of reaction conditions. The high degree of solubility of these molecules in THF is particularly noteworthy. It is cleaved with either aqueous HCl or by exchange with ethylenediamine in methanol. [reaction: see text]

A method for preparing DL-lysine

The invention provides a method for preparing DL-lysine with chiral lysine salt as a raw material. The method specifically comprises the following steps: dissolving chiral lysine salt in an acetic acid water solution, adding salicylaldehyde or benzaldehyde as a catalyst, carrying out heating and racemization, removing solvents through vacuum distillation after racemization is completed, washing a residual solid with ethanol, obtaining DL-lysine salt, removing salt with an ion exchange column and carrying out concentration and decoloration, thus obtaining a DL-lysine solid. The preparation method has the advantages that the preparation method is lower in production cost and simple in process; pollution is not easily caused in the production process; the racemization rate of L-lysine hydrochloride can be 100%; the purity of the obtained DL-lysine finished product is more than 98%.

PROBLEM TO BE SOLVED: To prevent a sealing member from breaking away from a device body even when the sealing member is bent. SOLUTION: A toner replenishing type developing device 4Y, 4M, 4C or 4B comprises a developing device body 4a, and a sealing member 4e. The sealing member 4e comprises an insertion and removal part 41a which a toner replenishing pipe 13Y, 13M, 13C, or 13B is inserted into and removed from, and a bending part 41b which bends by the insertion of the replenishing pipe 13Y, 13M, 13C or 13B into the insertion and removal part 41a, and is restored to its original state by the removal of the toner replenishing pipe 13Y, 13M, 13C or 13B from the insertion and removal part 41a. The bending part 41b of the sealing member 4e is formed in such a manner that the thickness t2 thereof in the insertion direction of the toner replenishing pipe 13Y, 13M, 13C or 13B at the bending part 41b is smaller than the thickness t1 of the insertion and removal part 41a in the insertion direction of the toner replenishing pipe 13Y, 13M, 13C or 13B at the insertion and removal part 41a.
