The C1-C7 and C9-C14 subunits of (+)-discodermolide have been synthesized using ruthenium-SYNPHOS-mediated asymmetric hydrogenation reactions of β-keto esters to set the C3, C5 and C11 hydroxy-bearing stereocenters with very high levels of diastereoselectivity.
利用钌-SYNPHOS 介导的δ-酮酯不对称氢化反应合成了 (+)-discodermolide 的 C1-C7 和 C9-C14 亚基,以极高的非对映选择性确定了 C3、C5 和 C11 含羟基的立体中心。
