An improved synthesis of gamma-hydroxybutenolides 1a-d was achieved via crossed aldol condensation between aldehydes 2a-d and the protected gamma-hydroxy-beta-methylbutenolides 3 or 4 using the bulky Lewis acid, aluminum tris(2,6-diphenylphenoxide) (ATPH). Using this same methodology, the gamma-hydroxybutenolides 17a-d having various heteroaromatic rings were synthesized and their anti-tumor activities
使用庞大的路易斯酸三(2,6-二苯酚铝)铝,通过醛2a-d与受保护的γ-羟基-β-甲基丁烯化物3或4之间的交叉羟醛缩合反应,可以提高γ-羟基丁烯化物1a-d的合成效率( ATPH)。使用相同的方法,合成了具有各种杂芳族环的γ-羟基丁烯内酯17a-d,并评估了它们的抗肿瘤活性。
