An enantioselective synthesis of (-)-slaframine (1) has been accomplished by an intramolecular azide [2 + 3] dipolar cycloaddition starting from the readily available aldehyde 12.

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. Sterically unbiased chiral aldehydes
