| 摘 要： | By using Beckmann rearrangement on alumina to prepare 7α-acetylamino-6, 14-endo-etheno-tetrabydrothebaine (2a) and its N-allyl analogue (2b) from the corrssponding ketoxime tosylates (1a and 1b), we obtained novel isoxazoline by-products (3a and 3b). Their structures were determined by IR, ^1H NMR, MS and elemental analyses. The mechanism of this side reaction was beiefly discussed.
