Syntheses of novel chiral quinoxaline derivatives from seco-derivatives of monoterpene hydrocarbons 3-carene and α-pinene
Abstract
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-acetylcyclo-butaneacetonitrile as starting materials.
