Abstract
The microwave-enhanced synthesis of 10-substituted isoalloxazines is achieved rapidly (˜4 min) and in good yield (>80–95%) via the cyclocondensation of 2-substituted aminoanilines with alloxan or N-methylalloxan monohydrate in the presence of acidic alumina or montmorillonite clays (KSF and K10).
