The first example of the title reaction involving the combination of an aryl aldehyde, norbornene, and silane has been developed (see scheme). The reaction involves aromatic CH bond activation of an aryl aldehyde at the ortho position, it proceeded with good diastereoselectively, and is applicable for various aryl aldehydes and norbornenes or norbornadienes. cod=cycloocta‐l,5‐diene, THF=tetrahydrofuran
已经开发了涉及芳基醛,降冰片烯和硅烷的组合的标题反应的第一个例子(参见方案)。该反应涉及在邻位的芳基醛的芳香族CH键活化,该反应 具有良好的非对映选择性,适用于各种芳基醛和降冰片烯或降冰片二烯。cod =环辛基-1,5-二烯,THF =四氢呋喃,NHC = N-杂环卡宾。
