A new metal-free oxidative decarbonylative [3+2] annulation of terminal alkynes with tertiary alkyl aldehydes is presented, which features broad substrate scope and excellent selectivity. The selectivity of this reaction toward cyclopentenes and indenes relies on the nature of the aldehyde substrates. While treatment of tertiary γ,δ-unsaturated aldehydes with common terminal alkynes assembles cyclopentenes
提出了一种新型的末端炔烃与叔烷基醛的无金属氧化脱羰基[3 + 2]环合反应,该方法具有广泛的底物范围和优异的选择性。该反应对环戊烯和茚的选择性取决于醛底物的性质。用常见的末端炔烃处理叔γ,δ-不饱和醛可组装环戊烯,而2-甲基-2-芳基丙醛则可成功获得茚基。
