(matrix presented) Treatment of N-acyloxazolidinones with hydroxylamines using samarium triflate as a Lewis acid provides the corresponding hydroxamic acids in 50-98% yields at room temperature. The conversion proceeds with high degree of chemoselectivity and without racemization of chiral centers α- to the acyl group.
CYCLIC ARYL HYDROXAMIC ACIDS, DERIVATIVES THEREOF AND METHOD OF USE AS ANTI-ALLERGY AGENTS
-
, (2008/06/13)
Cyclic aryl hydroxamic acids and derivatives thereof are provided having the structure STR1 wherein R is H or arylalkyl, and including acid-addition salts thereof. These compounds are useful as inhibitors of leukotriene production and as such are useful a
Boron Chelates of N-Substituted Hydroxamic Acids
Kliegel, Wolfgang,Nanninga, Dierk
, p. 2616 - 2629 (2007/10/02)
Boron chelates 2 - 6 are synthesized from N-alkyl- or N-arylhydroxamic acids 1 and various boron compounds that are capable of being chelated by bidentate ligands.The spectroscopic data correspond to the cyclic B,N-betaine structure of 2 - 6 and reflect the Lewis acidity of the chelated borenium ions as well as the extent of electron delocalization in the hydroxamate ligands.
