    Abstract: 我們成功以鈀金屬催化含氮炔類化合物進行分子內合環形成環戊
    烷取代吡咯衍生物,且使用微波反應器輔助可以有效提升產率,最高可
    達92%。此方法可應用於合成藥物Ramipril 中的重要結構。;Hydroamination of N-(2-ethynylcyclopentyl)sulfonamide to
    give non-aromatic 2,3-dihydropyrroles was achieved by using
    PdCl2 as the catalyst. With microwave-assisted heating, up to 92%
    isolated yield was obtained from this intramolecular 5-endodig
    cyclization. The cyclopentane-fused 2,3-dihydropyrroles were
    transformed into the corresponding N-tosyl-pyrrolidine-2-
    carboxylic acids.
