Galvez, Alberto Osuna published the artcileChemoselective Acylation of Primary Amines and Amides with Potassium Acyltrifluoroborates under Acidic Conditions, SDS of cas: 39546-32-2, the publication is Journal of the American Chemical Society (2017), 139(5), 1826-1829, database is CAplus and MEDLINE.
Amides, imides, acylguanidines, an acylcarbamate, an acylsulfonamide, and acylureas were prepared chemoselectively by reaction of aroyltrifluoroborates with primary amines using dichlorodimethylhydantoin or with primary amides, tert-Bu carbamate, guanidines, ureas, or methanesulfonamide using trichlorocyanuric acid (TCA) in buffered aqueous THF at pH 3; chemoselective acylation of primary amines and amides occurred in the presence of alcs., carboxylic acids, and even secondary amines. Streptomycin, gentamicin C1, and polymyxin B were chemoselectively acylated using the method, showing its potential utility in later-stage functionalization reactions.
