acids in a highly stereocontrolled manner. The reaction presumably proceeds through a bicyclic transition state. The alpha-carboxylic substituent exerts a remarkable effect on the rate, regio- and stereoselectivities of the reaction; homoallylic alpha-hydroxycarboxylic acids are formed with regio- and stereoselectivities approach 100%.
巴豆基硼酸酯与α-氧代羧酸以高度立体可控的方式反应。该反应大概通过双环过渡态进行。α-羧基取代基对反应的速率,区域选择性和立体选择性具有显着影响。形成均一的α-羟基羧酸,其区域和立体选择性接近100%。
