The delta-lactone boronolide (+)-1, a pharmacologically active, naturally occurring product, has been synthesized in enantiopure form with L-erythrulose as the chiral starting material. The key steps of the synthesis were a highly stereoselective aldol-reduction one-pot sequence, an indium-mediated diastereoselective aldehyde allylation, and a ring-closing metathesis.
δ-内酯硼烷内酯(+)-1是一种药理活性的天然产物,已以对映纯形式与L-赤藓糖为手性原料合成。合成的关键步骤是高度立体选择性的醛醇还原一锅序列,铟介导的非对映选择性醛烯丙基化和闭环易位。
