A hitherto unreported route for the synthesis of anthranilate esters is demonstrated using 2-nitrobenzaldehyde, malonitrile and an alcohol or amine via a metal and oxidant free multicomponent reaction (MCR) strategy.
A facile and efficient ring opening of isatin has been achieved by electrochemical anodic oxidation directly at room temperature. The results show that a constant current electrolysis of isatins in an undivided cell affords both the ester group and the urea group simultaneously. This reaction opens a new avenue for the synthesis of methyl 2-ureidobenzoates, enriches the research on the reactions of
