improved generation of chiral cationic iridium catalysts for the asymmetricisomerization of primaryallylicalcohols is disclosed. The design of these air‐stable complexes relied on the preliminary mechanistic information available, and on Charton analyses using two preceding generations of iridium catalysts developed for this highly challenging transformation.

A second generation of chiral (P,N)-iridium catalysts--readily accessible from inexpensive L-serine--displays expanded scope for the asymmetricisomerization of primaryallylicalcohols.
