Ueda, Mitsuru; Oikawa, Hideaki published the artcile< 1,2-Benzisoxazol-3-yl diphenyl phosphate: a new, reactive activating agent for the synthesis of amides, esters, and peptides via condensation>, SDS of cas: 21725-69-9, the main research area is benzisoxazolyl phosphate preparation condensation agent; amidation agent benzisoxazolyl phosphate; esterification agent benzisoxazolyl phosphate; peptide coupling agent benzisoxazolyl phosphate.
Title agent I was prepared and used to activate carboxylic acids (e.g., benzoic, hexanoic, and cinnamic acids) prior to amidation or esterification. One- and two-step procedures are given. I was also shown to be useful as a peptide-forming reagent; eleven protected dipeptides esters were prepared
Journal of Organic Chemistry published new progress about Amidation. 21725-69-9 belongs to class isoxazole, and the molecular formula is C7H5NO2, SDS of cas: 21725-69-9.
