Reaction of trimethylsilyl derivatives with Meldrum's acid : A new and easy monofunctionalization of malonic acid

日期:1989.1
Treatment of Meldrum's acid with silylated derivatives (amines, lactams or alcohols) yields very easily monofunctionalized malonic silyl esters. Hydrolysis of these silyl esters leads to the corresponding monoacids with a very good yield.
