The proline-catalyzed asymmetric aldol reaction between aliphatic aldehydes and acetone has, to date, remained underdeveloped. Challenges in controlling this reaction include avoiding undesired side reactions such as aldol condensation and self-aldolization. In recent years we have developed optimized conditions, which enable high yields and good to excellent enantioselectivities, and which are presented

An enantioselective approach to (+)-(S)-[n]-gingerols (1a–c) has been developed. The requisite stereogenic centers of target molecules are facilely constructed by the proline-catalyzed cross-aldol reaction from readily available achiral starting materials.
对(+)-(S)-[ n ]-姜酚(1a – c)的对映选择性方法已经开发出来。靶分子的必需立体异构中心是由脯氨酸催化的交叉羟醛缩合反应轻松地从容易获得的非手性原料中构建的。
