摘要

α-Bromooximes such as α-bromoacetophenone oxime and ethyl 3-bromo-2-(hydroxyimino) propanoate react with enamines to give 5, 6-dihydro-4H-1, 2-oxazines in good yields. Dihydro-1, 2-oxazine derivatives are also obtained by the reaction of α-bromooximes with vinyl ethers and silyl enol ethers in the presence of Na 2 CO 3. Dihydro-1, 2-oxazines can be converted into pyrrole derivatives via reductive deoxygenation by treating with Fe 3 (CO) ...
