Ringopening of 2-methyleneaziridines with Grignard reagents in the presence of CuI yields metalloenamines in a regiospecific fashion which can be further reacted with electrophiles to produce functionalised ketones via a one-pot process.
在 CuI 存在下用格氏试剂开环 2-亚甲基氮丙啶以区域特异性方式产生金属烯胺,该金属烯胺可以进一步与亲电试剂反应,通过一锅法生产官能化酮。

An efficient gold(I)-catalyzed alkenylation of β-alkyne-substituted pyrroles is reported. The intramolecular reaction gives straightforward access to different types of seven-membered-ring-fused pyrroles with endo-selectivity, and the intermolecular reaction with alkynes provides functionalized pyrrole derivatives.

methyleneaziridines with o-, m-, and p-acetylpyridines proceeds very smoothly in the presence of a palladium catalyst, affording the biologically very important o-, m-, and p-pyridinylpyrrole derivatives in good to high yields. Not only ortho, meta, and para, but also related substrates, such as acetyl aromatics and hetarenes, can be used as the starting acetyl derivatives to synthesize related compounds to pyridinylpyrrole
