Montmorillonite clays Mannich reaction

Another type of pre-formed reagent (28) has been used to carry out diastereose-lective Mannich reactions. The lithium salts 27 are treated with TiCU to give 28, which is then treated with the enolate of a ketone." ° The palladium catalyzed Mannich reaction of enol ethers to imines is also known." ° The reaction of silyl enol ethers and imines is catalyzed by HBF4 in aqueous methanol." ° Similarly, silyl enol ethers react with aldehydes and aniline in the presence of InCla to give the p-amino ketone." ° Imines react on Montmorillonite KIO clay and microwave irra-...
