(Chemical Equation Presented) Asymmetric aldol reaction: A domino silylation-aldol reaction between enoyloxazolidinones and various aldehydes has been developed (see scheme). The process catalysed by a copper complex in the presence of a borosilane led to high diastereoselectivities. Yields between 59 and 90 % and d.r. values between 78:22 to 95:5 were obtained. When methacryloyloxazolidinones were used, a controlled chiral quaternary carbon was generated. BPin=4,4,5,5-tetramethyl-1,3,2dioxaborolan-2-yl.
