conditions. A high-yielding, one-pot, three-component synthesis of functionalized 2-amino-4H-pyrans from β-dicarbonyl compounds, activated cyanomethylene compounds, and aldehydes, mediated by potassium-exchanged zirconium hydrogen phosphate [α-Zr(KPO4)2], is reported. The protocol shows excellent versatility, as it can be applied to aromatic, aliphatic, or α,β-unsaturated aldehydes under solvent-free conditions
摘要 由钾交换磷酸氢锆[α-Zr(KPO)介导的由β-二羰基化合物,活化的氰基亚甲基化合物和醛类合成的高产一锅三组分功能化2-氨基-4 H-吡喃4)2 ],被报告。该协议具有出色的通用性,因为它可以在无溶剂条件下应用于芳族,脂族或α,β-不饱和醛。 由钾交换磷酸氢锆[α-Zr(KPO)介导的由β-二羰基化合物,活化的氰基亚甲基化合物和醛类合成的高产一锅三组分功能化2-氨基-4 H-吡喃4)2 ],被报告。该协议具有出色的通用性,因为它可以在无溶剂条件下应用于芳族,脂族或α,β-不饱和醛。
