3-cinnamoyl-2-styrylchromones in excellent yields. The low solubility of the target molecules allows convenient isolation. The formation of an α,α-dicinnamoylated acetophenone, as a consequence of a two-fold Baker-Venkataraman sequence, has to be anticipated.
一种高效而直接的一锅法序列可以以极好的收率获得高度官能化的 3-肉桂酰基-2-苯乙烯基色酮。目标分子的低溶解度允许方便的分离。必须预料到由于双重 Baker-Venkataraman 序列而形成 α,α-二肉桂酰化苯乙酮。
