Optically active allylic sulphides 10–13, bearing two different leaving groups, react with organocopper reagents by selective substitution of the heterocyclic moiety leading to optically active homoallylic pivalates with chemo-, regio- and enantio- control. This selectivity seems to be related to the coordination exerted by the heterocyclic nucleus towards the organometal.
带有两个不同离去基团的旋光性烯丙基硫化物10-13通过选择性取代杂环部分而与有机铜试剂反应,从而导致旋光性,区域性和对映体控制的旋光性均戊酸新戊酸酯。这种选择性似乎与杂环核对有机金属的配位作用有关。
