Stereoselective total synthesis of α,β-unsaturated lactone (1a), isolated from Ravensara crassifolia, has been achieved efficiently starting from chiral 2,3-O-isopropylidene-d-glyceraldehyde (3) followed by asymmetric allylation and ring-closing metathesis. The antiproliferative activities of compounds 1a, 1b and the unusual bicyclic compound 2 were evaluated against three-cancer cell lines, THP-1
α的立体选择性全合成,β不饱和内酯(1A)中,从分离罗文莎云杉,已经实现了有效地从起始手性2,3- ö异亚丙基d甘油醛(3接着不对称烯丙基和闭环复分解)。评估了化合物1a,1b和不寻常的双环化合物2对三种癌细胞系THP-1和U-937(白血病)和A-375(黑色素瘤)的抗增殖活性。
