lignan naturalproducts have enticed significant effort in the exploration of new methodologies for their total synthesis. We have prepared γ-butyrolactone oximes from readily available δ-nitro alcohols via Boc2O mediated cyclization. The mild conditions are compatible with a wide range of functional groups, and this methodology has been applied to the total synthesis of five lignan natural products
木酚素天然产物的多样化结构和深刻的生物活性吸引了人们对其全合成新方法的探索。我们通过 Boc 2 O 介导的环化反应,由容易获得的 δ-硝基醇制备了 γ-丁内酯肟。温和的条件与广泛的官能团相容,该方法已应用于五种木脂素天然产物的全合成。
