Oxidative Cleavage of C2–C3 Bond in Isatin Using (Diacetoxyiodo)benzene: A Facile Synthesis of Carbamates of Alkyl Anthranilates
摘要:
On reaction with (diacetoxyiodo)benzene, isatin and N-acetyl isatin undergo the oxidative C2-C3 bond cleavage to form carbamates of alkyl anthranilates and alkyl 2-acetamidobenzoate, respectively.

The Hofmann-type rearrangement of aromatic and aliphatic imides using a hypervalent iodine(III) reagent generated in situ from PhI, m-CPBA, and TsOH·H2O proceeded in the presence of a base in alcohol to provide anthranilic acid derivatives and amino acid derivatives in high yields, respectively. This reaction proceeds through a tandem reaction via alcoholysis followed by a Hofmann rearrangement promoted

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.
On reaction with (diacetoxyiodo)benzene, isatin and N-acetyl isatin undergo the oxidative C2-C3 bond cleavage to form carbamates of alkyl anthranilates and alkyl 2-acetamidobenzoate, respectively.
