Rearrangements nitrogen

Raggatt ME, Simpson TJ, Wrigley SK (1999) Biosynthesis of XR587 (Streptopyrrole) in Streptomyces rimosus Involves a Novel Carbon-to-Nitrogen Rearrangement of a Proline-Derived Unit. Chem Commun 1039... [Pg.493]

The attempts to isolate the intermediate 1,2-A-sulfonylaziridine 53 were unsuccessful. Nucleophilic attack of the acceptor 9 at C-l opens the aziridine the nitrogen rearranges to the C-2 position and yields the desired tetrasaccharide 18. [Pg.277]

A different kind of reaction is observed in case of the photochemical and thermal reaction of an a-diazo-j -methoxy carbonyl acylphosphonate. The carbene formed after the loss of nitrogen rearranges to a ketene, by exclusive migration of the phosphoryl group (equation 83). ... [Pg.691]
