This communication discloses the first examples of aza-Wacker cyclizations of sulfamate esters. Within the realm of related cyclization reactions, this protocol is differential in that it forms six-membered rings in good yield and uses catalytic amounts of palladium(0) rather than palladium(II) salts. These reactions scale well, and their products are demonstrated to be valuable synthetic intermediates.

氨基磺酸盐氧化环化到侧链烯烃上。

该通讯公开了氨基磺酸酯的氮杂-瓦克环化的第一个例子。在相关环化反应领域内，该协议的不同之处在于它以良好的产率形成六元环，并使用催化量的钯 (0) 而不是钯 (II) 盐。这些反应规模很大，它们的产物被证明是有价值的合成中间体。
