We report a general preparation of heteroarylmethylzinc chlorides by direct zinc insertion into heteroarylmethyl chlorides, along with a facile and straightforward synthesis of these heterocyclic chloromethyl precursors. We demonstrate that heteroarylmethylzinc reagents undergo various reactions including cross-couplings, allylations, acylations, and addition reactions to aldehydes, leading to polyfunctional
我们报告了通过直接将锌插入杂芳基甲基氯化物中,以及这些杂环氯甲基前体的简便直接合成方法,来制备杂芳基甲基氯化锌的一般方法。我们证明,杂芳基甲基锌试剂会经历各种反应,包括交叉偶联,烯丙基化,酰化和与醛的加成反应,从而导致多官能杂环产物。此外,这些杂芳族锌化合物被证明是用于制备各种N和O杂环的通用试剂,并且可以使用CB1修饰剂的类似物。
