Payne oxidation

P. Koll and D. Eisermann, 1,6-Anhydrofuranoses. 20. Synthesis of two 1,6 2,3-dianhydrohexofuranoses by Payne oxidation of l,6-anhydro-5-0-benzoyl-2,3-dideoxy-/l-D-eryt/jro-hex-2-enofuranose and 1,6-anhydro-5-0-benzoyl-2,3-dideoxy-a-L-tAreo-hex-2-enofuranose, J. Carbohydr. Chem., 7 (1988) 757-771. [Pg.181]

MCPBA is the reagent most commonly used for alkene epoxidation. Payne oxidation (H O / CUjCN) is a convenient and inexpensive alternative. In the course of a study of the enantioselective enzymatic hydrolysis of 6, Takeshi Sugai of Keio University has described Tetrahedron Lett. 2007, 48, 979) a practical procedure for multigram Payne epoxidation of 5. [Pg.38]

Sharpless and Masumune have applied the AE reaction on chiral allylic alcohols to prepare all 8 of the L-hexoses. ° AE reaction on allylic alcohol 52 provides the epoxy alcohol 53 in 92% yield and in >95% ee. Base catalyze Payne rearrangement followed by ring opening with phenyl thiolate provides diol 54. Protection of the diol is followed by oxidation of the sulfide to the sulfoxide via m-CPBA, Pummerer rearrangement to give the gm-acetoxy sulfide intermediate and finally reduction using Dibal to yield the desired aldehyde 56. Homer-Emmons olefination followed by reduction sets up the second substrate for the AE reaction. The AE reaction on optically active 57 is reagent... [Pg.59]

The native iron-sulfur clusters of many enzymes can be directly observed by EPR spectroscopy (Beinert, 1978). In several cases, appearance of the DNIC signal from nitrogen oxide-treated enzyme (Salerno et al., 1976 Dervartanian et al., 1973 Hyman et al., 1992) or cells (Reddy et al., 1983 Payne et al., 1990) results in the disappearance of these native signals, indicating conversion of the iron from the native cluster coordination to DNIC complexes. However, loss of EPR signal from native clusters does not necessarily correlate with appearance of the DNIC signal (Hyman et al., 1992). [Pg.147]

The pathway for the reduction of nitrate by denitrifiers is generally recognized to involve four steps as shown in Eq. (1) (Betlach and Tiedje, 1981 Braun and Zumft, 1991 Goretski and Hollocher, 1990 Knowles, 1982 Payne, 1981). The N-oxides represented. [Pg.293]
