Abstract: A process for the synthesis of an Exochelin comprising the steps of generating L-N-[(2-benzyloxy-(benzoyl)] serine or L-N-[2-benzyloxy (benzoyl)] threonine, creating L-N-t-Boc-.epsilon.-hydroxynorleucine and reacting same to produce L-N-Boc-.epsilon.-bromonorleucine trimethylsilylethyl ester, providing a dicarboxylic acid and forming an O-benzyl methyl hydroxamate from the dicarboxylic acid, coupling the O-benzyl methyl hydroxamate with the L-N-Boc-.epsilon.-bromonorleucine trimethylsilylethyl ester to give an L-N.sup.2 -Boc-N.sup.6 -methyl,N.sup.6 -(benzyloxy) lysine 2-trimethylsilylethyl ester which incorporates the dicarboxylic acid as modified above, removing the N-tert-butoxycarbonyl protecting group from the L-N.sup.2 -Boc-N.sup.6 -methyl, N.sup.

Abstract: A method and a composition for disinfecting matter or materials such as medical instruments, operating rooms, examining tables, walls, windows, floors, solutions, porous substances and the like contaminated with bacteria, bacterial spores, fungi, or viruses is disclosed. The composition consists of a mixture of a peroxymonosulfate and a carbonyl-containing compound and reaction products thereof and is preferably dioxirane formed by in situ oxidation of a ketone or aldehyde by the peroxymonosulfate in aqueous solution. Carbonyl-containing compounds that have been tested include acetone, 2-pentanone, 4-hydroxy-4-methyl-2-pentanone, and camphorsulfonic acid. The method includes providing a solution containing the dioxirane reaction mixture and contacting the matter or materials with it at room temperature for a time sufficient to disinfect and sterilize the matter or materials.
