Palladium-Catalyzed Synthesis of 2,3-Disubstituted 5-Azaindoles via Heteroannulation Reaction and of 2-Substituted 5-Azaindoles through Domino Sila-Sonogashira/5-Endo Cyclization
A general and efficient procedure for the synthesis of 2,3-disubstituted 5-azaindoles through the palladium-catalyzed heteroannulation of 4-acetamido-3-iodopyridines and diaryl-, dialkyl-, or arylalkylalkynes is described along with a study of the reaction regioselectivity. The preparation of 2-monosubstituted 5-azaindoles via sila-Sonogashira/5-endo cyclization is also reported. These methods allowed

The present invention relates to a compound of formula (I) or a stereoisomer, or tautomer, (I) wherein A1, A2, R1 and R2, have the same meaning as that defined in the claims and the description. The present invention also relates to compositions, in particular pharmaceuticals, comprising such compounds, and to uses of such compounds and compositions for the prevention and/or treatment of an infection caused by pestivirus in an animal.
An efficient heterogeneous copper-catalyzed cyclization of o-haloanilides and metalsulfides has been achieved via the C–S coupling in DMF at 80 or 140 °C in the existence of an MCM-41-bound NHC-Cu(I) catalyst and then intramolecular condensation, delivering a wide range of substitutedbenzothiazoles in mostly good to high yields. This new MCM-41-NHC-CuI complex can facilely be obtained by a two-step
