This is a new example of a nonmetallic small-molecule catalyst for direct intermolecular aldol reactions. We found L-lysine is an effective catalyst for this condensation between unmodified acetone and a variety of aldehydes in the presence of pure water. This green catalyst system could be reused.
这是一个非
金属小分子催化剂用于直接分子间醛醇反应的新实例。我们发现
L-赖氨酸是有效的催化剂,可以在纯
水存在下促进未改性
丙酮与多种醛之间的缩合反应。这个绿色催化系统可以重复使用。
