panoyl chlorides afforded in good yields the corresponding 2-coumarinyloxypropanals. Their subsequent aldolic condensation with 3(2H)-furanones, followed by dehydration, led to enantiopure geiparvarin analogues now being investigated as promising antitumoral compounds.
描述了对映体纯的2-香豆酰氧基丙醛的新的方便途径:Rosenmund还原(R)-或(S)-2-香豆酰氧基丙酰氯的产率很高,提供了相应的2-香豆酰氧基丙醛。他们随后与3(2 H)-呋喃酮的醛缩合反应,然后脱水,导致对映纯的geiparvarin类似物被研究为有希望的抗肿瘤化合物。
