摘要:
Alkyl substituted or unsubstituted, bicyclic keto acids may be prepared by cyclizing unsaturated, cyclic dicarboxylic acid anhydrides in the presence of a strong Bronsted acid catalyst. The products may be useful as corrosion inhibitors in alcohol fuels and as intermediates in petroleum, pharmaceutical and additive manufacture.
