项目摘要
Highly stereoselective syntheses of chiral bicyclic [3.1.0] compounds have been developed by several methods. On a way of this research project, some total syntheses of natural products were also achieved by a palladium-mediated biaryl coupling reaction of phenyl benzoate derivatives.1.A Reaction of σ-Symmetric Ketone CompoundsA symmetric ketone was prepared as the substrate, through the Meinwald rearrangement of norbornadiene. An enentioselective deprotonation reaction was attempted using several chiral amide bases. This reaction was quite successful to produce an optically active bicycle[3.1.0] compound with high enantioselectivity.Next, a symmetric epoxyketone was examined on the enantioselective deprotonation reaction using chiral amide bases. This reaction was also successful to generate the corresponding enolate followed by a transannular carbon-carbon bond formation accompanying an epoxy opening. The obtained product was transformed into the optically active bicyclo[3.1.0] compound with high optical purity.2.Optical Kinetic Resolution Using the Baker's YeastAn optical kinetic resolution of a racemic bicyclo[3.1.0] compound using the baker's yeast was attempted. After various examination of the reaction conditions and work-up methods, we found that this technique was effective to give the optical active bicycle[3.1.0] compound with high stereoselectivity. The optical purity and the absolute configuration were determined by comparison with a reported information.
手性双环[3.1.0]化合物的高立体选择性合成已经通过多种方法得到了发展。在本研究项目中,还通过钯催化的苯甲酸苯酯衍生物的联芳基偶联反应实现了一些天然产物的全合成。1.σ对称酮化合物的反应通过降冰片二烯的Meinwald重排反应合成了对称酮。尝试了几种手性酰胺碱的对位选择性去质子化反应。该反应成功地合成了具有光学活性的具有高对映选择性的双[3.1.0]化合物。其次,考察了对称环氧酮与手性酰胺碱的不对称去质子化反应。该反应还成功地生成了相应的烯酸酯,随后在环氧开孔的同时形成了跨环碳-碳键。将所得产物转化为高光学纯度的光学活性双环[3.1.0]化合物。2.面包酵母拆分外消旋双环[3.1.0]化合物。通过对各种反应条件和合成方法的考察,我们发现该方法能有效地合成具有高立体选择性的光学活性化合物[3.1.0]。通过与文献报道的信息比较,确定了产物的光学纯度和绝对构型。
