Double crossed-aldol condensation of a variety of aromatic aldehydes with 1,3-dioxan-5-one in the presence of magnesium bromide diethyl etherate and diethylamine at room temperature is described. Excellent yields of 4,6-bis(arylmethylidene)dioxan-5-ones are achieved in a facile, one-pot, general procedure. The structure and the Z, Z-configuration of the exocyclic double bonds of the products were determined
描述了在溴化二乙醚合镁和二乙胺存在下,多种芳香醛与 1,3-dioxan-5-one 在室温下的双交叉羟醛缩合反应。4,6-双(芳基亚甲基)二恶烷-5-酮的高产率是在一个简单的一锅法通用程序中实现的。产物环外双键的结构和Z、Z构型分别通过光谱法和X射线晶体学测定。
