摘要：

SmI2-promoted reduction of alpha-allenyl nitro derivatives 2a-f using controlled conditions provides either 3-amino-4-vinylidenetetrahydrofuran 3a or 3-hydroxylamino-4-vinylidenetetrahydrofurans 4b-f, which undergo intramolecular cyclization consistent with a reverse Cope elimination to afford 3,6-dihydro-1,2-oxazines 5b-f.
