Oxetanes offer exciting potential as structural motifs and intermediates in drug discovery and materials science. Here an efficient strategy for the synthesis of oxetane rings incorporating pendant functional groups is described. A wide variety of oxetane 2,2‐dicarboxylates were accessed in high yields, including functionalized 3‐/4‐aryl‐ and alkyl‐substituted oxetanes and fused oxetane bicycles. Enantioenriched
氧杂环丁烷作为药物发现和材料科学中的结构基序和中间体具有令人兴奋的潜力。这里描述了一种合成含有侧链官能团的氧杂环丁烷环的有效策略。以高产率获得了多种氧杂环丁烷 2,2-二羧酸酯,包括功能化的 3-/4-芳基和烷基取代的氧杂环丁烷和稠合氧杂环丁烷双环。对映体富集的醇提供具有完全保留构型的对映体富集的氧杂环丁烷。氧杂环丁烷产品被进一步衍生化,而环保持完整,从而突出了它们作为药物化学基石的潜力。
