The synthesis of a series of alpha-methylene-gamma-butyrolactones (compounds 4a, 4b, 6-12, 16, 17) and alpha,beta-unsaturated-delta-lactones (compounds 19-23, 25, 26) starting from 4,4-dimethyldihydrofuran-2,3-dione (1) has been described. Their chemical structures were assigned by spectroscopic evidence. These new compounds exhibited significantly different antiproliferative properties against cultured
从4开始合成一系列α-亚甲基-γ-丁内酯(化合物4a,4b,6-12、16、17)和α,β-不饱和δ内酯(化合物19-23、25、26)已经描述了,4-二甲基二氢呋喃-2,3-二酮(1)。其化学结构由光谱证据确定。这些新化合物对培养的人类肿瘤细胞系表现出显着不同的抗增殖特性,它们的IC(50)值范围从0.88到> 20.00 microM。
