N-Acyliminium ion cyclizations were studied with allenylmethylsilanes to synthesize nitrogen heterocycles. N-Acyliminium ion cyclizations were carried out by exposure of precursors 6 and 7 to Lewis acid. The precursors 6 were converted to pyrrolizidinone derivatives 9 with an exo-allene moiety, while the precursors 7 to indolizidinone derivatives 10 with an exo-1,3-diene moiety.
用烯丙基甲基硅烷研究了N-酰基亚胺离子的环化反应,以合成氮杂环。通过使前体6和7暴露于路易斯酸来进行N-酰基亚胺离子的环化。将前体6转化为具有外-异戊烯部分的吡咯烷酮衍生物9,而将前吲哚吲哚酮酮衍生物10的前体7转化为具有exo-1,3-二烯部分。
