Sc(OTf)3-promoted [5 + 1] cycloaddition of vinylcyclopropanes with PhINTs is reported, enabling the regioselective preparation of a range of 1,2,3,6-tetrahydropyridine scaffolds under mild conditions. This represents the second example of a [5 + 1] nitrene-transfer cycloaddition and exhibits complementary substrate scope to the antecedent work, expanding the range of N-heterocycles accessible via this
据报道,具有PhINT的Sc(OTf)3促进乙烯基环丙烷的[5 +1]环加成反应,使在温和条件下区域选择性制备一系列1,2,3,6-四氢吡啶骨架。这代表了[5 +1]氮转移环加成反应的第二个实例,并且在前期工作中显示了互补的底物范围,从而扩大了通过该策略可及的N杂环的范围。
