The synthesis of a range of novel ynone trifluoroborates has been achieved, in a two-pot process from propargylic alcohols. These alkynes have been subsequently used in the formation of a range of pyrazole trifluoroborate salts via cyclization with hydrazines. The products are generated with high levels of regiocontrol and in excellent yields and represent versatile synthetic intermediates.
在两锅法中,由炔丙基醇合成了一系列新型的三氟硼酸炔酮。这些炔烃随后已通过与肼的环化作用用于形成一系列吡唑三氟硼酸盐。该产品产生的区域控制水平高,收率高,代表了多种合成中间体。
