Stereoselective epoxidation and bromoalkoxylation with 3-ylidenepyrazine-2,5-diones

Bartels, Annett,Jones, Peter G.,Liebscher, Jürgen

, p. 67 - 72 (2003)

3-Ylidenepyrazine-2,5-diones 1 were stereoselectively epoxidsed by dimethyldioxirane giving access to spirooxiranes 2 and diols 3. Bromohydroxylation and bromoalkoxylation of 3-ylidenepyrazine-2,5-diones 1 produced high yields of optically active 3-(1-bro
