Synthesis and Rearrangement of N -Organyloxy ,-Lactams Derived from a (4+2)/(3+2) Sequential Cycloaddition Reaction Involving Enol Ethers and Nitro Alkenes

Abstract The synthesis of N -organyloxy ,-lactams 2 by treatment of nitroso acetals 1 with a base is discussed. Based on the formation of a by-product, a mechanism for the rearrangement to N -organyloxy ,-lactams is proposed. This mechanism is supported by trapping of the intermediate acyl nitro compound 8 with dimethylamine. Furthermore, it was discovered that upon more forcing basic conditions these N -organyloxy ,-lactams can rearrange further to 3-organyloxy ,-lactams. By using a series of structurally diverse N -organyloxy ,-lactams the generality of this novel rearrangement is demonstrated. A mechanism for the conversion of N -organyloxy ,-lactams to 3-organyloxy ,-lactams is proposed. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004) [source]

The unexpected rearrangement of 1,5-benzodiazepin-2,4-dione to a benzimidazol-2-one derivative during N,N' -diglucosylation

JOURNAL OF HETEROCYCLIC CHEMISTRY, Issue 6 2004
Brahim Lakhrissi
Reaction of 1,5-benzodiazepin-2,4-dione with 3- O -substituted-5,6-anhydro-1,2-isopropylidene-,-D-glucofuranose gave the unexpected N,N' -di-glucofuranosyl benzimidazol-2-one by a novel rearrangement and ring closure reaction. A mechanism is proposed. [source]
