Azidohydrins rearrangement

A novel approach to the synthesis of lactams has been reported56 which involves reaction of such enol ethers with TMS-azide to give (triisopropylsilyl)azidohydrins, which then undergo a photoinduced Schmidt rearrangement (equation 14). [Pg.1673]

The reaction with a ketone gives an azidohydrin intermediate, which rearranges to form an amide ... [Pg.207]

In some cases the ring expansion involves the rearrangement of an azidohydrin intermediate (equation l). [Pg.345]

Reaction of ketones with hydrazoic acid gives azidohydrin intermediates, which undergo rearrangement to form amides. ... [Pg.354]

Allylic fra i-l,2-azidohydrins prepared by Lewis-acid-catalysed ring opening of cyclic vinyl epoxides with sodium azide via an 5 2 mechanism have been found to isomerize to trans-l,4-azidohydrins via a suprafacial allyl azide [3,3]-sigmatropic rearrangement (Scheme 16). ... [Pg.525]
