Oxidative cycloaddition of hydroxamic acids with dienes or guaiacols mediated by iodine(III) reagents [PDF]

Beilstein Journal of Organic Chemistry, 2018
[Bis(trifluoroacetoxy)iodo]benzene (BTI) and (diacetoxyiodo)benzene (DIB) efficiently promote the formation of acylnitroso species from hydroxamic acids in the presence of various dienes to give the corresponding hetero-Diels–Alder (HDA) adducts in ...

Methylation of 2-Aryl-2-(3-indolyl)acetohydroxamic Acids and Evaluation of Cytotoxic Activity of the Products

Molbank, 2021
2-Aryl-2-(3-indolyl)acetohydroxamic acids demonstrate promising antitumor activity, but quickly metabolize in vivo via glucuronidation of hydroxamic acid residue. In an attempt to improve their pharmacokinetics, methyl esters were synthesized via a newly
