5-ALKYL-5-[2-(O-IODOPHENYLCARBAMOYL)VINYL] DERIVATIVES OF MELDRUM ACID AS SUBSTRATES FOR THE INTRAMOLECULAR HECK REACTION - APPLICATION TO THE SYNTHESIS OF CARBAZOLES
A. Arcadi et al., 5-ALKYL-5-[2-(O-IODOPHENYLCARBAMOYL)VINYL] DERIVATIVES OF MELDRUM ACID AS SUBSTRATES FOR THE INTRAMOLECULAR HECK REACTION - APPLICATION TO THE SYNTHESIS OF CARBAZOLES, Synlett, (10), 1993, pp. 743-744
The palladium-catalyzed cyclization of 5-alkyl-5-[2-(o-iodophenylcarba
moyl)vinyl] derivatives of Meldrum's acid produces 3-alkylidene oxindo
les containing the Meldrum's acid moiety. These compounds can be usefu
l synthetic intermediates. An application to the synthesis of function
alized carbazoles through the intermediacy of 3,5,6-trisubstituted 2H-
pyran 2-ones is reported.
