A straightforward multicomponent Knoevenagel-aza-Michael-cyclocondensation reaction involving readily available hydroxamic acid-derived from naturally occurring α-amino acids allows a diversity-oriented synthesis of novel isoxazolidin-5-ones possessing an N-protected α-amino acid pendant with good to high diastereoselectivities thanks to a match effect with a chiral organocatalyst. These diversely substituted heterocycles, easily isolated as a single diastereoisomer, proved to be versatile platforms for the formation of an array of α/β-dipeptide fragments.
Effective synthesis of enantiopure hydroxamates by displacement of resin-bound esters with hydroxylamine
Thouin, Eryk,Lubell, William D.
, p. 457 - 460 (2000)
Enantiopure hydroxamic acids have been synthesized by nucleophilic displacement of carboxylates linked to oxime resin using hydroxylamine in a MeOH:CHCl3 solution.

Paragraph 0149, (2018/12/11)
Disclosed are amino acid mimetics that possess antibiotic properties in prokaryotic cells. These mimetics are coupled to one or more optionally substituted amino acids provided that at least one of the amino acids is an optionally substituted amino acid s

A continuous flow tubing reactor can be used to readily transform methyl or ethyl carboxylic esters into the corresponding hydroxamic acids. Flow rate, reactor volume, and temperature were optimized for the preparation of a small collection of hydroxamic acids. Synthetic advantages were identified as an increased reaction rate and higher product purity. This method was also successfully applied to the multistep preparation of suberoylanilide hydroxamic acid, a potent HDAC inhibitor used in anticancer therapy.
