An efficient and practical total synthesis of (+)-spirolaxine methyl ether is described. The phthalide-aldehyde 3 has been prepared via the Diels−Alder reaction between 1,4-unconjugated diene 5 and a long-chain acetylenic dienophile 6. The carbon framework of spiroketal sulfone 4 has been constructed from monobenzyl protected 1,5-pentanediol and the stereochemistry in both the phthalide portion and
描述了一种有效和实用的全合成(+)-螺菌灵甲基醚。邻苯二甲醛-醛3是通过1,4-非共轭二烯5与长链炔属二烯亲和体6之间的Diels-Alder反应制得的。螺环酮砜4的碳骨架是由单苄基保护的1,5-戊二醇构成的,并且通过Sharpless不对称环氧化作用已建立了邻苯二甲酸酯部分和螺环酮部分的立体化学。
