converted in a sequence of O-protection, reduction, O-activation, thioether and ether formation and deprotection to chiral, non-racemic β,β′-dihydroxy thioethers 1a, 1b and ether 1c. Overall yields are excellent (75%). In an attempt to synthesize the respective dihydroxy ether 1d derived from mandelic acid 1,3-dioxolane derivatives 7 were obtained.
天然α-羟基酸已经按照O-保护,还原,O-活化,硫醚和醚形成和脱保护的顺序转化为手性,非外消旋的β,β'-二羟基硫醚1a,1b和醚1c。总体收率极好(75%)。为了合成相应的衍生自扁桃酸1,3-二氧戊环衍生物7的二羟基醚1d。
