The fully regioselective reactivity of four new highly substituted silyl aryl triflate aryne precursors in aryne acyl-alkylation, acyl-alkylation/condensation, and heteroannulation reactions is reported. The application of these more complex arynes provides access to diverse natural product scaffolds and obviates late-stage functionalization of aromatic rings.
报道了四种新的高度取代的甲硅烷基芳基三氟甲磺酸芳基芳烃前体在芳烃酰基烷基化,酰基烷基化/缩合和杂环化反应中的完全区域选择性反应性。这些更复杂的芳烃的应用使人们可以使用多种天然产物支架,并避免了芳环的后期官能化。
