摘要:The subject invention provides methods for the chemical synthesis of racemic arsinothricin (D,L-AST), the novel organoarsenical antibiotic. One is by condensation of the 2-chloroethyl(methyl)arsinic acid with acetamidomalonate, and the second involves reduction of the N-acetyl-protected derivative of hydroxyarsinothricin (AST-OH) and subsequent methylation of the resulting sodium salt of trivalent arsenic intermediate with methyl iodide. The enzyme AST N-acetyltransferase (ArsN1) was utilized to purify L-AST from racemic AST. This expedient chemical synthesis of AST provides a source of this novel antibiotic for future drug development.

摘要:The present invention relates to a base catalyzed sequential conjugate addition reaction for the synthesis of a novel and efficient co-initiator for Photo Induced Radical Polymerization. The process comprises synthesis of new co-initiator having 6,5 and 6,6-bicyclic scaffolds as central core. The process comprises reacting thiocarboxylic acid, catechol, thiocatechol, benzodithiol, benzothiocatechol and binol with ketone substrates at room temperature with a base and a solvent to yield the novel co-initiator compound of Formula 3, Formula 5, Formula C and Formula Z.
