Good levels of 1,4-anti asymmetric induction are obtained in the TiCl3(i-PrO)-mediated aldol reaction of chiral α-benzyloxy methyl ketones with a wide array of aldehydes. This methodology represents a new approach to substrate-controlled acetate aldol reactions capable of providing highly functionalized fragments in a straightforward manner, which may be useful in the design of more efficient syntheses
在手性α-苄氧基甲基酮与多种醛的TiCl 3(i- PrO)介导的羟醛反应中获得了良好水平的1,4-抗不对称诱导。这种方法学代表了一种新的方法,可进行底物控制的乙酸羟醛醛缩反应,该方法能够以直接的方式提供高度官能化的片段,这可能对设计更有效的合成方法有用。
