A Biocatalytic Aza-Achmatowicz Reaction
A catalytic, enzyme-initiated (aza-) Achmatowicz reaction is presented. The involvement of a robust vanadium-dependent peroxidase from Curvularia inaequalis allows the simple use of H2O2 and catalytic amounts of bromide.
متن کاملMicrowave accelerated aza-Claisen rearrangement.
A study of microwave-induced and standard thermal Overman rearrangement of selected allylic trichloroacetimidates 1a-1f, 6-8 to the corresponding acetamides 2a-2f, 9-11 is reported. The microwave-assisted rearrangement of trifluoroacetimidate 13 is also described. Using this methodology, an efficient access to versatile allylic trihaloacetamides building synthons was established.
متن کاملSynthesis of 4-aza-5,6-dimethylbenzimidazole and biosynthetic preparation of 4- and 7-aza-5,6-dimethylbenzimidazolylcobamide.
We report on the preparation of 4-aza-5,6-dimethylbenzimidazolylcobamide and 5,6-dimethyl-7-azabenzimidazolylcobamide. These vitamin B12-analogs were required as reference compounds for comparison with a corrinoid previously isolated in small amounts for Eubacterium limosum grown in the presence of 4(5)-aminoimidazole. 4(7)-Aza-5,6-dimethylbenzimidazole was synthesized from N-1-benzyl-4-nitroim...
متن کاملSynthesis of polyfluoroalkyl cyclobutenes from 3-aza-1,5-enynes via an aza-Claisen rearrangement/cyclization cascade.
A facile synthetic route to access polyfluoroalkyl functionalized cyclobutenes bearing an exo cyclic double bond from 3-aza-1,5-enynes is reported. The reaction proceeds via a thermal aza-Claisen rearrangement to give an allene-imine intermediate; subsequent cyclization affords the cyclobutene core. The kinetics of the transformation of starting material and the intermediate was studied by (1)H...
متن کاملnatomy and Pathophysiology of Spinal Cord njury Associated With Regional Anesthesia nd Pain Medicine
r w t m s i a a t t t c t t p A u s L i he American Society of Regional Anesthesia and Pain Medicine (ASRA) convened a panel in April 005 to create a Practice Advisory on the Neurologic omplications of Regional Anesthesia and Pain Medcine. This review deals with the pathophysiology of pinal cord injury. The Practice Advisory recommenations are based on extensive review of existing anmal and hum...
