Syntheses of novel chiral quinoxaline derivatives from seco-derivatives of monoterpene hydrocarbons 3-carene and α-pinene

The preparation of substituted quinoxaline derivatives bearing a terpenoid substituent in the quinoxaline nucleus has been described, using (1R,3S)-2,2-dimethyl-3-(2-oxopropyl)cyclopropaneacetonitrile and (±)-(1S^*,3S^*)-2,2-dimethyl-3-acetylcyclobutaneacetonitrile as starting materials.
