The intramolecular bromoamination of allylated aldoxime ethers leads first to isoxazolidinium salts which then undergo a skeletal rearrangement to form bromo-5,6-dihydro-4H-1,3-oxazines. Aliphatic aldoxime ethers with α-protons undergo multiple brominations before rearrangement.

Diastereoselective bromocyclization of O-allyl-N-tosyl-hydroxylamines.

The Journal of organic chemistry

The intramolecular bromoamination of O-allyl-N-tosyl-hydroxylamines results in the formation of isoxazolidines via selective 5-endo-tet cyclization. This process occurs trans-selectively in high yield and diastereoselectivity. The obtained bromo-isoxazolidines provide access to other useful building blocks, such as 2-azido-aminoalcohols, diaminoalcohols, and...
