| Research Abstract |
Ubiquitous metals like iron and bismuth have been found to act as very reactive borderline catalysts due to their π- and σ-acidities. Based on these characteristics, intramolecular carbo-oxycarbonylation of 3-alkynyl esters, pyrrole synthesis from 2-propynylamines and 1,3-diketones, cyclization of alkenyl N,O-acetals, alkynylcyclopropanation of 1,6-enynes, and intramolecular hydroarylation of alkynes have been succeeded very effectively under mild conditions, which provide new synthetic methods for many useful heterocycles.
