Synthesis and Transformations of Nitrones for Organic Synthesis

“…C-Phenyl-N-phenylsulfonyloxaziridine (Davis reagent), 55,56 has also been used; however, the laborious and potentially unsafe Davis oxidation is replaced by a safe, reproducible, and scalable oxidation using m-chloroperbenzoic acid (m-CPBA). 57,58 Biomimetic catalytic oxidation can be performed with molecular oxygen and hydrazine hydrate in 2,2,2-trifluoroethanol with organocatalyst, 3-methyllumiflavinium perchlorate (FlEt + •ClO 4 − ; method L). 59−61 It is noteworthy that various nitrones have been used as key intermediates for natural product synthesis 52,62,63 as shown in Figure 1.…”

“…The method is useful because of tolerance with a variety of functional groups. C -Phenyl- N -phenylsulfonyloxaziridine (Davis reagent), , has also been used; however, the laborious and potentially unsafe Davis oxidation is replaced by a safe, reproducible, and scalable oxidation using m -chloroperbenzoic acid ( m -CPBA). , …”

Postawy Społeczne Jako Element Kapitału Społecznego a Proces Readaptacji Społecznej Skazanych

“…Do tej grupy można zaliczyć definicję W.M. Fusona, który określa postawę, jako "prawdopodobieństwo wystąpienia określonego zachowania" 23 , jak również "operacyjną definicję" D. Campbella, zgodnie z którą "po- [11] stawa społeczna jednostki jest (trwałym) syndromem reakcji zgodnych względem pewnej grupy społecznych przedmiotów" 24 .…”

AMIDE FORMATION BY DECARBOXYLATIVE CONDENSATION OF HYDROXYLAMINES AND a-KETOACIDS: N-[(1S)-1 PHENYLETHYL]-BENZENEACETAMIDE

“…N -Hydroxy-( S )-1-phenylethylamine oxalate was prepared from ( S )-1-phenylethylamine following a reported procedure 2. The oxalate salt of the hydroxylamine was recrystallized from hot ethanol and washed with ethyl ether.…”
