are fungicidal. When two ortho-substituents are present, stable atropisomers can be isolated. Several methods for resolving racemic intermediates into the enantiomers are described, including separations of diasteromeric ester derivatives and diasteromeric salts. The intermediates were converted into products in which the absolute configuration can be correlated to biological activity.
某些邻位取代的苯基三唑酮化合物是杀真菌的。当存在两种邻位取代基时,可以分离出稳定的阻转异构体。描述了几种将外消旋中间体拆分为对映异构体的方法,包括分离非对映体酯衍生物和非对映体盐。中间体被转化为其中绝对构型可以与生物活性相关的产物。
