Abstract
The aerobic oxidation of alcohols and synthesis of quinoxalines was developed in a one-pot biomimetic approach using recyclable ruthenium on charcoal and randomly methylated β-cyclodextrin in water under neutral conditions overcoming many of the drawbacks in the earlier methodologies. The catalytic system can be recycled up to five cycles without loss of activity.
Key words
alcohols - biomimetic synthesis - cyclodextrins - oxidation - Ru/C
