Treatment of aliphatic carbonyl compounds with trimethylsilyl chloride with Mg turning for Grignard reaction without any pre-treatment in N,N-dimethylformamide at room temperature brought about highly facile, effective and stereoselective coupling to give the corresponding silyl enol ethers in good yields.
在室温下,在N,N-二甲基甲酰胺中不进行任何预处理的情况下,用三甲基甲硅烷基氯将镁转为格氏反应来处理脂族羰基化合物,可实现高度简便,有效和立体选择性的偶联,从而以良好的收率得到相应的甲硅烷基烯醇醚。
