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

Tetrakis(triphenylphosphine)palladium(O) [or palladium acetate and added triphenylphosphine] catalyzes the carbonylation of methyleneaziridines to α-methylene-β-lactams at room temperature and one atmosphere.
A microchannel reactor-based continuous flow method for synthesizing diverse C-acyloxy-substituted aziridines has been developed, allowing for rapid and efficient synthesis within seconds.
