  Potassium Boc-Protected Secondary Aminomethyltrifluoroborates: Synthesis and Suzuki–Miyaura Cross-Coupling Reactions

  摘要：

  Seven potassium Boc-protected secondary aminomethyltrifluoroborates were prepared in a standardized two-step process. The Suzuki-Miyaura cross-coupling reaction was studied with this new class of nucleophiles, and a large variety of aryl and hetaryl chlorides provided the desired products in good to excellent yields, thereby allowing easy access to secondary aminomethyl substructures.

  N-tert-butoxycarbonylation of a variety of amines using diphenylglycoluril as organocatalyst has been described.

  and convenient synthetic protocol for the selective t-butyl carboxylation of aliphatic, aromatic and heterocyclic amines using AmberlystR A 21 catalyst; a mild basic solid resin under solvent free conditions is reported. This method explores several advantages such as reusability of the heterogeneous catalyst, cleaner reaction profile, mild and solvent free system, short reaction time, operational simplicity

  使用AmberlystRA 21催化剂进行脂族，芳族和杂环胺选择性叔丁基羧化的高效，环保，便捷的合成方案；据报道，在无溶剂条件下，一种温和的碱性固体树脂。该方法探索了多种优点，例如多相催化剂的可重复使用性，更清洁的反应曲线，温和无溶剂的系统，反应时间短，操作简便，转化率高，产物收率高以及催化剂成本低。此外，由于该催化剂是弱碱性的，因此如路易斯酸催化的N-Boc保护的情况下，如果长时间持续反应，则未观察到所形成的氨基甲酸酯的分解。这使得本方案对于胺的N-Boc保护是有用的且有吸引力的。
