Reaction of 3-ylidene-2,5-diketopiperazines 1 with 3,3-dimethyldioxirane (2) gives enantiomerically pure spiro-annelated epoxides 3, which are chiral pyruvate derivatives.
Stereoselective epoxidation and bromoalkoxylation with 3-ylidenepyrazine-2,5-diones
Bartels, Annett,Jones, Peter G.,Liebscher, Jürgen
, p. 67 - 72 (2007/10/03)
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
