[Structure: see text] Treatment of an N-4-pentenyl or N-5-hexenyl urea with a catalytic 1:1 mixture of a gold(I) N,N-diaryl imidazol-2-ylidine complex and AgOTf at or near room temperature leads to intramolecular exo-hydroamination to form the corresponding nitrogen heterocycle in excellent yield.
[结构:见正文]用N,N-二芳基咪唑-2-基金(I)金和AgOTf的1:1催化混合物处理N-4-戊烯基或N-5-己烯基尿素室温导致分子内外加氢胺化,从而以优异的收率形成相应的氮杂环。
