In this paper, we show the substrate 4-(trimethylsilyl)-3-butyn-2-one is unstable, and can be easily cleaved into a carbonyl alkyne and trimethylhydroxysilane in aqueous buffer with pH above 6.0. However, this problem could be effectively solved by lowering the buffer pH. Meanwhile, the efficient synthesis of enantiopure (S)-4-(trimethylsilyl)-3-butyn-2-ol, a key intermediate for preparing a 5-lipoxygenase...
