Exposure of 1H-pyrazole-1-alkanoic acids to two equivalents of n-butyllithium affords the corresponding cyclic ketones via a Parham-type cyclization process. Although yields are modest, this procedure represents a simple and direct intramolecular acylation of a non-nucleophilic pyrazole carbon.
将 1H-吡唑-1-烷酸与两当量的正丁基锂接触,通过帕勒姆式环化过程生成相应的环酮。虽然产量不高,但这一过程代表了一种简单直接的非亲核吡唑碳分子内酰化反应。
