Iridium catalysts with bicyclic pyridine-phosphinite ligands: Asymmetric hydrogenation of olefins and furan derivatives

(Chemical Equation Presented) Superior bicyclics: Iridium catalysts as 1 derived from pyridine-phosphinite ligands considerably extend the scope of asymmetric hydrogenation. In addition to various unfunctionalized and functionalized olefins, furans, and benzofurans, for which no catalysts were known before, are also hydrogenated with high enantioselectivity (see scheme).

Fragmentation of Cyclic Carboxonium Ions, IV. - Synthesis of β-Oxa-γ, δ-enones

The proton-catalyzed fragmentation of 4-methylene-1,3-dioxolanes 2 by weak acids (pK > 4.3) or weak acidic ion exchangers leads in good yields to β-oxa-γ, δ-enones 5 which are thus easily and generally available for the first time.
