The structures of two new ionone glucosides from Melia toosendan and a novel type of selective bio-oxidation.
摘要:
The structures of two new ionone glucosides, melia-ionosides A and B, isolated from leaves of Melia toosendan were determined based on the combined evidence of chemical, spectral, and X-ray studies. In addition, a novel type of selective bio-oxidation was found during the chemical study.
