A synthetic strategy to access hexasubstituted γ-lactones via i) aerobic radical cyclization, ii) allylation, and iii) translactonization has been developed. The key to this sequence is the highly diastereoselective aerobic carbooxygenation based on the integration of endothermic intramolecular radical addition to geminally disubstituted alkenes with exothermic oxygenation to synthesize α,α,β,β-tetrasubstituted
已经开发出一种通过 i) 有氧自由基环化、ii) 烯丙基化和 iii) 反内酯化获得六取代的 γ-内酯的合成策略。该序列的关键是基于对孪生二取代烯烃的吸热分子内自由基加成与放热氧化的整合的高度非对映选择性有氧碳氧化,以合成α,α,β,β-四取代的γ-内酯。
