Synthesis of Six-Membered Heterocycles via the Ring Cleavage of α-Bromo-γ-butyrolactone Promoted by Organotin Alkoxide

Shibata, Ikuya,Toyota, Mitsuki,Baba, Akio,Matsuda, Haruo

, p. 486 - 488 (2007/10/02)

Novel six-membered heterocyclic compounds, such as tetrahydro-1,3-oxazin-2-ones 10a-e, 2-imino-1,3-oxathiane (11), and tetrahydro-2-imino-1,3-oxazine (12) are prepared by the ring cleavage of α-bromo-γ-butyrolactone, promoted by organotin alkoxide.
