We established a convergent synthesis of S-8921 (1), a unique hypocholesterolemic lignan analog, in 9 steps, including concise preparations of phthalide 7 and acylpropenoate 10, and their regio- and stereocontrolled tandem anionic reactions leading to precursor 11 as a key step.
我们通过9个步骤建立了S-8921(1)的聚合合成,S-8921(1)是独特的降胆固醇的木脂体类似物,包括邻苯二甲酸酯7和酰基丙烯酸酯10的简洁制备及其区域和立体控制的串联阴离子反应,这是关键的前体11。
