alkyne-selective hydroboration of 1,3-enynes is disclosed, providing access to the previously elusive 2-boryl-1,3-dienes. Using CuOAc, Xantphos, and HBpin, Bpin was installed on the internal carbon of a series of symmetric and nonsymmetric 1,3-enynes, affording products with excellent Z:E selectivity. The utility of the 2-boryl-1,3-diene products was demonstrated by transformation to useful functional groups
公开了铜催化的1,3-烯炔的炔烃选择性硼氢化反应,提供了获得先前难以捉摸的2-硼基-1,3-二烯的途径。使用CuOAc、Xantphos和HBpin,将Bpin安装在一系列对称和非对称1,3-烯炔的内部碳上,使产物具有优异的Z : E选择性。 2-硼基-1,3-二烯产品的实用性通过转化为有用的官能团得到证明。
