β-unsaturated amides and alkenyl nitriles from readily available propargylic alcohols. The reaction proceeded smoothly under the neutral conditions with hydroxylamine hydrochloride (NH2OH·HCl) as the nitrogen source. The development of these new strategies has significantly extended the application of hydroxylamine hydrochloride to the chemistry of propargylic alcohols. Moreover, both secondary and tertiary alcohols
我们已经开发出一种高度选择性的方法,可以从容易获得的炔丙醇中合成α,β-不饱和酰胺和烯基腈。在中性条件下,以盐酸羟胺(NH 2 OH·HCl)为氮源,反应平稳进行。这些新策略的发展极大地扩展了羟胺盐酸盐在炔丙醇化学中的应用。此外,仲醇和叔醇都已被高度区域选择性地转化为具有良好官能团相容性的所需产物。
