alcohol anion equivalent and leads to three-carbon elongations of various electrophiles by introduction of a fully protected hydroxypropenyl moiety. The latter contains a double bond, which can be unravelled to the cis configuration by diastereoselective removal3 of the dimethylene-disulfur bridge, as well as a protected primary hydroxyl group that, depending on the deprotection conditions used (DDQ/NaBH4
在最近的论文2中,我们报道了3 C锂化的5,6-二氢-1,4-二硫代-2-基[(4-甲氧基苄基)氧基]甲烷(1)的设计和合成。烯丙基醇阴离子当量,并通过引入受完全保护的羟基丙烯基部分,导致各种亲电试剂的三碳延伸。后者包含一个双键,该双键可通过非对映选择性去除二亚甲基-二硫桥的3分解为顺式构型,以及一个受保护的伯羟基,具体取决于所用的脱保护条件(DDQ / NaBH 4或DDQ) ,可能导致游离的烯丙醇或α,β-不饱和醛。
