Stereocontrolled route to the δ-benzylidenemethyl-β-hydroxy-δ-lactone system has been developed utilizing a new epoxyacetylene building block prepared from optically active epichlorohydrin. The present synthesis allowed efficient construction of goniothalamin in natural and unnatural forms and its 3-hydroxy derivative having the essential anti-β/δ-stereochemistry for HMG Co-A reductase inhibition.
利用由光学活性表氯醇制备的新型环氧乙炔结构单元,开发了立体控制的δ-亚苄基甲基-β-羟基-δ-内酯体系。本发明合成物可以有效地构建天然和非天然形式的Goniothalamin及其具有对HMG Co-A还原酶抑制至关重要的抗-β/δ-立体化学的3-羟基衍生物。
