A stereoselective synthesis of ABT-100 1, a novel farnesyl transferase inhibitor, is described. The key step involves a stereoselective addition of the heterocyclic zinc reagent 10 to chiral α-keto ester 9 in >10:1 diastereoselectivity using menthol as the chiral auxiliary. Crystallization of the product as the dimeric zinc complex facilitates isolation of product in >99:1 dr. The biaryl linkage is
描述了一种新型法呢基转移酶抑制剂ABT-100 1的立体选择性合成。关键步骤涉及使用薄荷醇作为手性助剂,以大于10:1的非对映选择性将杂环锌试剂10立体选择性地添加到手性α-酮酯9中。作为二聚体锌络合物的产物结晶有助于在> 99:1 dr。通过仅使用0.06mol%的催化剂的Suzuki偶合形成联芳基键。使用二醇5和芳基氟化物4之间的S N Ar反应完成两个片段的偶联。五步序列的总产率为千克规模的37%。
